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 
https://issues.asterisk.org/view.php?id=0  0xb7f6d410 in __kernel_vsyscall ()

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

Use poll() instead of select() in res_timing_pthread to avoid stack
corruption.

This code did not properly check FD_SETSIZE to ensure that it did not try
to
select() on fds that were too large.  Switching to poll() removes the
limitation
on the maximum fd value.
