The following package has been updated in the Cygwin distribution:
This is an update to the final(?) 2007 release of dmalloc. This is also
the first dmalloc package for 64-bit Cygwin.
dmalloc is a malloc debugger. It is a drop in replacement for the
system's `malloc', `realloc', `calloc', `free' and other memory
management routines that provides powerful debugging facilities
configurable at runtime. These facilities include such things as
memory-leak tracking, fence-post write detection, file/line number
reporting, and general logging of statistics.

Notes on using dmalloc with Cygwin
IGNORE ALL CYGWIN SPECIFIC SECTIONS OF THE OFFICIAL DMALLOC
DOCUMENTATION AND WEB SITE. All Cygwin workarounds documented there are
As the Cygwin DLL uses malloc and creates helper threads, it is
recommended to use the threaded version of the library even if your
program does not use threads.
Due to the way interposition of memory management functions is
implemented in Cygwin, dmalloc will report the calling file/line
location as a wrapper function in Cygwin's malloc_wrapper.cc
The dmalloc utility program's feature to report debug flags as token
names seems to be broken, always reporting 'unknown token'
dmalloc does not support posix_memalign(). Debian has patches to add
this support, but as they are quite invasive, I haven't incorporated them.
dmalloc isn't the greatest malloc debugger. Don't expect miracles.
