That's probably 21.1p2. The reason you don't see it is that
glibc2.x systems XEmacs uses the system malloc instead of its own doug
lea allocator. The main reason for this is that we don't run into
obscure and hard to debug problems like this.
The Doug Lea or "new GNU malloc" is the system malloc when using glibc
or Linux libc5; it has not been cloned into the XEmacs core. The
so-called "new GNU malloc" in XEmacs is really the old GNU malloc, and
the "old GNU malloc" in XEmacs is really the very-old GNU malloc.

It works because the glibc startup code works by calling this hook
Who says the Solaris startup code will do that?
All Doug Lea malloc related stuff is guarded by ifdefs and are only enabled
if configure detects the presence of it. It should be absolutely safe to
apply the patch and it is better than voodoo_free_hook.
