emacs-unicode-2 bootstrap on FreeBSD (temacs coredump)

[Damien Deville <damien.deville@netasq.com>]

Hi emacs-devel,

On FreeBSD 6.2 with an up to date checkout of emacs-unicode-2 CVS temacs 
coredump while bootstraping.

`/bin/pwd`/temacs --batch --load loadup bootstrap
Segmentation fault (core dumped)
gmake[2]: *** [bootstrap-emacs] Error 139

Launching gdb on the core shows the following trace:

---Type <return> to continue, or q <return> to quit---

The rest of the backtrace contains the same recursive call to 
__malloc_initialize()


Thanks in advance,
