There's a package called Memory Watcher/memwatch designed for cygwin which
I've used.
I can't find a URL but this is from the README and a web search should find
it ...
Memory Watcher
==============
This is a little library for tracing memory related api calls on cygwin
using gcc.
Features:
- detection of unfree'd memory regions
- traces each malloc(), calloc(), realloc() and free() call
- collects size and addresses of allocated area
- runtime switchable logging support of hooked function

Subject: Memory debugging under cygwin
Hi all,
I have a program that segfaults, and it's quite obvious that this is
caused due to some memory corruption. Except it segfaults at a place
where, if running it in gdb, there shouldn't be a problem. There seems
to be some memory corruption somewhere, and I can't figure out where.
I tried linking the app with dmalloc, but I can't get it to generate a
log file, even if I explicitly request one by including calls to the
dmalloc library in the application. Valgrind doesn't seem to be
available on cygwin either.
Can anybody recommend a way to debug this sort of error? Are there any
other memory debuggers available that work with cygwin?
Maarten
