Summary:                    Random crashes
Description: 
Asterisk randomly crashes on me
I'm running Ubuntu Server and have tried asterisk 1.6.1.17 and 1.6.1.18

Asterisk randomly crashes, my first bt's pointed at

0x2449 out of bounds>, lineno=-1239132680, func=0x1 <Address 0x1 out of
bounds>,
    mutex_name=0x0, t=0xb62455f0) at
/usr/src/asterisk-1.6.1.18/include/asterisk/lock.h:731

But that is because of the stack protector, so i recompiled asterisk
without optimize and disabled the stack protector to generate the attached
backtrace

Thanks for the information! Would you mind providing some valgrind output
when you're reproducing the issue? Note that valgrind will make the system
incredibly slow, so you should only do this after hours or on a test
environment.

Thanks!
