Bug Report: Firefox 3.6.2 crashes on JavaScript heavy pages

The browser crashes on JavaScript intensive pages. I've tried to debug
the behavior but since firebug crashes with firefox this is a no go.
I've tried disabling optimizations in the firefox makefile but it
makes no difference.

I don't believe it matters but my hardware is a Dell XPS m1210 laptop
with intel graphics.

What system:
pylon# uname -a
FreeBSD pylon 8.0-RELEASE FreeBSD 8.0-RELEASE #0: Sat Mar 13 18:50:29
CET 2010 root@pylon:/usr/obj/usr/src/sys/PYLON i386

What makefile:
pylon# grep Makefile,v /usr/ports/www/firefox/Makefile
# $FreeBSD: ports/www/firefox/Makefile,v 1.221 2010/03/23 08:54:22 beat Exp $

How to reproduce:
I can reproduce this crash everytime by removing my .mozilla and then visit:
http://review.source.android.com/11633
Most pages are Ok.

Error message:
Floating point exception (core dumped)

Well.. the processor supports SSE instrincs, perhaps this is a SIMD
optimization bug somewhere else, I remember I enabled that for some
other port..

Other notable behaviour:
If i run firefox3 with truss -f firefox3 does not crash on the page.
I could probably dive deeper into this.
