Description:Since I enabled call recording in my ConfBridge bridge profile, after about every 5th held conference (sometimes after 3, sometimes after 10, it depends), when the last users exits the conference, Asterisk crashes. Is this a known error? I'm using Asterisk 10.7.1 on CentOS 64bit with the official RPMs.

Thank you for your bug report. In order to move your issue forward, we require a backtrace[1] from the core file produced after the crash. Also, be sure you have DONT_OPTIMIZE enabled in menuselect within the Compiler Flags section, then:

make install

After enabling, reproduce the crash, and then execute the backtrace[1] instructions. When complete, attach that file to this issue report.

[1] https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace

Core dumps are only useful on the machine they're created from.  You'll need to generate a backtrace using the instructions mentioned above.  Please make sure that you have DONT_OPTIMIZE enabled, and preferably, BETTER_BACKTRACES as well.

Hi Matt, thanks. I would like to do that and am trying to rebuild Asterisk with DONT_OPTIMIZE from the SRPM without success so far. I've posted on the asterisk-dev list, but didnt get much back. Maybe you can help me?

Not really.  If you're working outside of the Asterisk build system, there isn't much I can do to help you.  I would suggest either downloading the tarball from source at http://downloads.asterisk.org/pub/telephony/asterisk/ or follow Paul's suggestions.
