New version - 2.9.4, 19th November 2012

First, thanks for your hard work!

I've updated my Ubuntu 12.04 x64 today and since the reboot cgminer 2.9.* creates coredumps. Sad

Version 2.8.7 is working fine, 2.9.3 and 2.9.4 are not. The core dump is created randomly after 1 to 30 seconds after cgminer was started.

This is the gdb output:
