firefox 3.5 exited on signal 12

[Unga]

Hi all

I have installed firefox 3.5,1 port (make install clean) on FreeBSD 7.2 i386. Firefox crashes when it try to display Theora video (http://www-cs-faculty.stanford.edu/~nick/theora-soccer/) with following message on logs:
kernel: pid 1106 (firefox-bin), uid 1001: exited on signal 12 (core dumped)

Do others experience it? Is there a fix for this?

Best regards
Unga

Same here. It crashes...
pid 26921 (firefox-bin), uid 1001: exited on signal 12

You may need sem(4) loaded.  It's a module, so you can try it out
without rebuilding your kernel.

Rebuilt kernel with
options         P1003_1B_SEMAPHORES     # POSIX-style semaphores

Now it plays Theora video and does not crash any more.  :)

You can load sem.ko to the same effect, FWIW.  The UPDATING entry for
firefox3-devel mentions this in the following part:

  20090628:
    AFFECTS: users of www/firefox3-devel
    AUTHOR: gecko@...

    If your Firefox crashes with the following message while viewing a
    HTML5 page: "Bad system call (core dumped)" you need to load the sem
    module (kldload sem).

    To load sem on every boot put the following into your
    /boot/loader.conf: sem_load="YES"
