Yep. And that's what dmalloc does. :)

I've tried and failed a couple of times. Mind you I didn't try terribly
hard because the only time I needed it, inspection by eye found the bug
five minutes later.

valgrind leak detection might help as well, but I'm not sure that XEmacs
tries too terribly hard to free() all its memory if it's going to die
anyway (even an Fgarbage_collect() or whatever at the very end might
legitimately not free everything; a good few roots are static variables
which won't get freed.)

The one advantage of valgrind leak detection is that it's not going
to get broken by people doing strange things with malloc() :)
