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. Regards --=20 Edward Tj=F6rnhammar +46703784224 | http://cflags.cc
