Bug#700433: Iceweasel browser crashes with a Bus error message on a Debian sparc system (Debian Squeeze)

[Ivaylo Ganchev]

Package: iceweasel

Version: 10.0.12esr-1~bpo60+1

Iceweasel crashes systematically with a Bus error message on a
Debian-sparc machine. When invoked on the command line, the browser
starts, but it soon freezes and finally crashes.

debian version: 6.0.6
uname -a: Linux octopussy 2.6.32-5-sparc64-smp #1 SMP Sun Sep 23
11:15:08 UTC 2012 sparc64 GNU/Linux
libc6 version: 2.11.3-4

It is a Sun T1000 machine

Here is a trace found in the core file:

Reading symbols from /usr/lib/libaudiofile.so.0...(no debugging
symbols found)...done.
Loaded symbols for /usr/lib/libaudiofile.so.0
Core was generated by `/usr/lib/iceweasel/firefox-bin'.
Program terminated with signal 10, Bus error.
