----------------------------------------

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.

> The ast_activate_generator function in channel.c checks wether there exists an old generator and in that case, calls its release function. However, the ast_activate_generator function does not tidy up pointers, sets the timeout, etc. like the ast_deactivate_generator function does. As a result our Asterisk crashes at times, when it is under heavy load. It seems to be some kind of racing condition.
