测试内存泄露工具

2004-10-19  Gray Watson  <>

	* Releasing dmalloc version 5.4.2.

	* Refined the definition of the 'alloc-blank' and 'free-blank'
	tags.  The 'alloc-blank' token clear various parts of the
	allocation block when it is allocated.  The 'free-blank' token
	clears a pointer when it is freed.

	* Also, the library was clearing the user spaces of an allocated
	chunk with the alloc-blank character and the non-user spaces with
	the free-blank character.  This seemed confusing and wrong so now
	all sections of an allocated chunk are cleared with the
	alloc-blank character.

	* Fixed a couple of longer standing stupid bugs via feedback from
	Philippe.  Thanks dude.

2004-10-12  Gray Watson  <>

	* Releasing dmalloc version 5.4.1.

	* Found and fixed a stupid little test bug so re-released as 5.4.1.

2004-08-13  Gray Watson  <>

	* Fixed some missing ; and a int/unsigned-int bug from feedback
	from Joe Buehler.

2004-07-09  Gray Watson  <>

	* Removed force-linear token because made invalid with mmap
	addition.

	* Removed the growing up testing and other restrictions for the
	heap because mmap made it invalid.  Drastically reduced the
	various up and down macros and associated testing.

	* Added mmap usage inside of the library.  Should it be the
	default?

2004-07-08  Gray Watson  <>

	arg_check.c functions were not locking.  Ugh.  Thanks much to
	Guy (guyresh).

	* Added dmalloc_verify_pnt function for proper external pointer
	checking.

2004-01-14  Gray Watson  <>

	* Added a dmalloc_memory_allocated function to assist with the
	checking of the memory size start feature.

	* Added automatic checking of the start at file:line, iteration,
	and memory size features.

	checking the heap after we allocate a certain size of memory.

	more feedback from Richard Colley.
