测试内存泄露工具

	* Releasing dmalloc version 4.1.0 beta.

	* Moved some settings from chunk_loc.h into settings.dist.

	* Improved the handling of free(NULL) and malloc(0) settings.

	* Added initial memalign support with a error message if the
	alignment is less than block size which is not currently
	supported.

	* Renamed print-error token to print-messages.

Wed Oct 28 10:17:13 1998  Gray Watson  <>

	* Released dmalloc version 4.0.3.

	* Moved to #ident for rcs-ids in GCC.

	* Found and fixed a bug when reallocing a previous valloced
	section.  Not a good idea anyway since it will not preserve the
	block-aligned status (should it).

	* Released dmalloc version 4.0.2.

	* Fixed a problem in return.h and DMALLOC_UNKNOWN_FILE.  Ugh.
	Thanks much to Mike Sacauskis for pointing this out.

	* Added startup messages acknowledging the thread status.  Added
	error.o to the thread object list.

Wed Oct  7 14:52:14 1998  Gray Watson  <>

	* Fixed problem with thread compilation and chunk.c.  Thanks much
	to Didier Verna for pointing out this problem.

	sbrk calls.

	much harder to add.
