set check-overwrites 1

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'check-underwrites' detect underwrites [0]
% ----------------------------------------------------------------------
% same with writes below allocated data. You do not have to set this
% option if you only want detect 'off (below) by one' errors because
% ccmalloc keeps a magic value just before the user data.

set check-underwrites 1


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'check-free-space' can be used to find dangling pointers. [0]
% ----------------------------------------------------------------------
% A very serious type of bug is to write on data that has already been
% freed. If this happens the free space management of malloc is in
% trouble and you will perhaps encounter non deterministic behaviour of
% your program. To test this first enable 'keep-deallocated-data' and
% restart your program. If the problem goes away and ccmalloc does not
% report anything then you should *also* enable 'check-free-space'. Now
% ccmalloc checks already deallocated data for corruption.
%
% Note that to perform this check 'keep-deallocated-data' also must
% be enabled and 'only-count' disabled.

set check-free-space 1

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'check-interval' can be used to speed up checks [0]
% ----------------------------------------------------------------------
% If check-overwrite, check-underwrites or check-free-space is set then
% the default is to do 'write checks' when data is deallocated and
% to do 'free space checks' when reporting together with
% 'write checks' for garbage. When you want these checks to be
% performed more often then you should set 'check-interval' to a
% positive number. This number is the interval between the number of
% calls to free or malloc without performing the checks.

%set check-interval 0

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'check-start' can be used to speed up checks [0]
% ----------------------------------------------------------------------
% The flag 'check-start' delays the start of checks until the given
% number of calls to free and malloc have occured. Together with
% 'check-interval' you can use a binary search to find an aproximation
% when a corruption occured! If you simply set check-interval to 1 and
% check-start to 0 then this will slow done your program too much.

%set check-start 0

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'silent' disables banner [0]
% ----------------------------------------------------------------------
% If you don't want to see the banner of ccmalloc then set
% 'silent' to 1 (f.e. when logging to stderr)

%set silent

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'file-info' en/disables file and line number information [1]
% ----------------------------------------------------------------------
% If your program was compiled with debugging information (-g) then
% ccmalloc can generate line number and file info for call chains opening
% a pipe to gdb. For very big programs this method is slow. In this case
% you can set 'file-info' to zero and you will only get the function
% names. For SunOS 4.3.1 'nm' does not 'demangle' C++ identifiers
% very well. So gdb is called instead but only if 'file-info' is
% not set to 0.

%set file-info 1

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'continue' if ccmalloc aborts when something weired happened [0]
% ----------------------------------------------------------------------
% If the free function of ccmalloc is called with an argument that does
% not make sense to ccmalloc or that has already been freed then you
% probably want the program to stop at this point. This is also
% the default behaviour. But you can force ccmalloc also to ignore
% this if you set 'continue' to 1. This flag also controls the behaviour
% of ccmalloc when free space is found to be corrupted or a write
% boundary has been overwritten.

%set continue 0

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'chain-length' is the length of the maximal call chain [0 = infinite]
% ----------------------------------------------------------------------
% You can restrict the length of call chains by setting 'chain-length'
% to a number greater than zero. If 'chain-length' is zero (the default)
% then chains are as long as possible (on a non x86 system only call
% chains with a finite maximal length can be generated). For big
% programs especially if keep-deallocated-data is enabled this can
% reduce the size of the log file from over 100MB to several MB!

%set chain-length 0

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'print-addresses' of data [0]
% ----------------------------------------------------------------------
% If you want to see the addresses of the allocated data (and
% deallocated data if keep-deallocated-data is set to 1) set
% 'print-addresses' to 1.

%set print-addresses 0

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'print-on-one-line' shortens log file [0]
% ----------------------------------------------------------------------
% The default is to print function names and file/line number info
% on separate lines. With 'print-on-one-line' set 1 all are printed
% on one line.

%set print-on-one-line 0

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'additional-line' enlarges readability [1]
% ----------------------------------------------------------------------
% When printing call chains an empty line is printed between to
% call points. Set 'additional-line' to 0 to disable this feature.

%set additional-line 1

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 'statistics' enables more accurate profiling [0] 
% ----------------------------------------------------------------------
% Calculate number of allocations and deallocations and bytes also on
% a per call chain basis. This uses 4 additional pointers for each
% call chain.

set statistics 1

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% set order for sorting of call chains [1] [1]
% ----------------------------------------------------------------------
% When printing the report to the log file the call chains are sorted by
% default with respect to the largest accumulated garbage produced by
% that call chain. This can be changed with setting 'sort-by-wasted'
% to 0. In this case they are sorted by the number of allocated bytes.
% If you want the number of allocations (only possible if 'statistics'
% is enabled) as sorting criteria instead then set 'sort-by-size' to 0.

%set sort-by-wasted 1
%set sort-by-size 1

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% report library chains [0]
% ----------------------------------------------------------------------
% Some external libraries (like libg++) have memory leaks. On some
% systems even a call to printf produces a leak. ccmalloc tries to
% detect this (only heuristically!) and with this flag you can control
% if leaks produced by such library calls are reported.
%
% Since version 0.2.1 some similar effect can be achieved by using
% 'dont-log-chain' with no argument.

%set library-chains 0

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% print debugging information [X] (compile time dependend)
% ----------------------------------------------------------------------

%set debug X

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% align memory on 8 byte boundary [0] (no effect on SunOS or Solaris)
% ----------------------------------------------------------------------

%set align-8-byte 0

% only report allocations which ended up being wasted (i.e don't report
% allocations which were completely freed properly. ) [1]
