Valgrind mac now on trunk!

http://blog.mozilla.com/nnethercote/2009/05/28/mac-os-x-now-supported-on-the-valgrind-trunk/
says that Valgrind's trunk now supports the mac!

We've been using valgrind on the mac for several months now
on the Chromium project. We run some of our unit tests
constantly under Valgrind, and it has caught quite a few
leaks and other problems. I highly recommend it.

http://groups.google.com/group/vim_mac/msg/2bfd871b82c9b3b1 is a
walkthrough
showing exactly how to build and use it to track down a bug in mac
vim.
(Though that was done before the merge to trunk, so the download line
is a bit dated.)

Run, don't walk, to http://valgrind.org, check it out from the trunk,
and give it a shot.
