Illegal instruction in firefox/thunderbird with libpthread

[Joe Marcus Clarke]

I'm running -CURRENT:

FreeBSD gyros.marcuscom.com 5.2-CURRENT FreeBSD 5.2-CURRENT #33: Fri Jun
11 17:44:01 EDT 2004    
marcus at gyros.marcuscom.com:/usr/obj/usr/src/sys/GYROS  i386

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.
#1  0x2886a539 in _kse_setthreaded (threaded=-1077946880)

        curthread = (struct pthread *) 0x807e2b0
        new_thread = (struct pthread *) 0x807be00
        kse = (struct kse *) 0x0
        kseg = (struct kse_group *) 0x0
        crit = 0x1
        ret = 1
#3  0x2884b759 in PR_Select ()
   from /usr/X11R6/lib/thunderbird/lib/thunderbird-0.7/libnspr4.so
No symbol table info available.

This is highly reproduceable with thunderbird, and I can make the port
available if someone wants it.  Thanks.

Joe
