I'd love to have a copy! However, I really think that it should also be
built into libgmalloc. As you noted, and as mentioned on the failmalloc
page, too many people assume that their code will work correctly, 100% of
the time. Even Apple is doing it! :) I'd rather test, test, test, and then
test some more, so that my users don't get stuck with my bad code. Memory
testing should be put into libgmalloc for that reason.
So, I'm willing to work on the source for libgmalloc, if it is available for
download. Is it?
Thanks,
Cem Karan
