I'm running -CURRENT:
FreeBSD gyros.marcuscom.com 5.2-CURRENT FreeBSD 5.2-CURRENT #33: Fri Jun

And trying to port the new thunderbird. When I run it on a fresh
account, I immediately get an illegal instruction and a core dump. If I
libmap libpthread to libc_r or libthr, the problem goes away, and
thunderbird starts. If I then libmap libpthread back to libpthread, I
no longer get the problem. Therefore, it looks like one code path in
thunderbird (and one user has reported the same thing with firefox-0.9)
causes a crash with KSE. Here is the backtrace I have so far:
Illegal instruction (core dumped)
#0 0x28872477 in kse_create () at {standard input}:15
No locals.

No symbol table info available.
This is highly reproduceable with thunderbird, and I can make the port
available if someone wants it. Thanks.
