firefox 19.0,2 crashing under FreeBSD 8

[Craig Rodrigues]

Hi,

I reported this problem with firefox 19.0,1 under FreeBSD 7:

http://lists.freebsd.org/pipermail/freebsd-ports/2013-March/082090.html


Since FreeBSD 7 is not supported by the ports team, I did the following:

(1)  Upgraded my system to  FreeBSD 8 from the stable/8 branch in
Subversion at this revision:

r248839 | sbruno | 2013-03-28 10:27:46 -0700 (Thu, 28 Mar 2013) | 13 lines

(2)   Rebuilt world/kernel and reinstalled

(3)   Deleted all my ports

(4)   Upgraded ports tree with portsnap

(5)   Rebuilt all my ports.

I now have firefox-19.0,2.  However, when I run it, it still seems
to crash randomly.  I grabbed two stack traces by attaching
gdb to firefox.  The stack traces don't occur in the same place,
and seem to indicate stack corruption of some sort:

=========================================================

I saw in this thread:

http://lists.freebsd.org/pipermail/freebsd-ports/2013-February/081567.html

That patching clang helped fix some stack issues with Firefox.

Is this solution applicable to FreeBSD 8?
On FreeBSD 8, the firefox port is built with g++46, not clang.

Thanks.
