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 r...@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.

Doesn't crash for me on Firefox 3.5.8: # /etc/make.conf: CFLAGS += -fno-strict-aliasing -pipe CXXFLAGS+= -fno-strict-aliasing -pipe # ... CPUTYPE := nocona Do you have a custom make.conf file? If so, what's your processor and your CPUTYPE / C*FLAGS?

Re: Bug Report: Firefox 3.6.2 crashes on JavaScript heavy pages
Thank you for your replies! I didn't have any special make.conf but tried using fno-strict-aliasing as suggested by Garret and now it works.

Another possibility -- if you're using -O2, etc, it might be a compiler optimization bug on your CPU architecture (less likely).
