[gentoo-dev] emacs segfaults

[Burton Samograd]

I just did an update and now for some reason my emacs is segfaulting at 
startup.  I've tried unmerging it and installing different versions with 
no luck.  And, as luck would have it, the xemacs build script seems to have
problems too.

Here's an strace of emacs starting up:

Any ideas on what's happenning here?  I just emerged xfree yesterday (i was console only
before)...i'm thinking that has something to do with the new problems.
