I recently asked on the Valgrind mailing list about this very matter. This
is what Julian Seward, the author of Valgrind said:

XEmacs doesn't seem to work with Valgrind, but assuming it dumps the
executable in the same way, thats not surprising.

I tried building Emacs with -DSYSTEM_MALLOC, --with-x-toolkit=no, and even
--without-x (but not all combinations) to no avail.
I feel the code that causes a problem is probably in unexec.c, or possibly
emacs.c but this is just a guess and not a very educated one at that.
