Description:Sometimes after sip reload asterisk is crashing and generating core. My setup is: sip friends and logs are in mysql database. Handler for config and log is unix_odbc. I've changed for trial log handler to cdr_mysql but nothing has changed. I've examined core and got:

Core was generated by `/usr/sbin/asterisk -vvvg -c'.
Program terminated with signal 11, Segmentation fault.

We're going to need a longer backtrace than that.  Please upload the full output of 'bt full' in a separate text file.

In this same core, type:

(gdb) frame 1
(gdb) list

and upload the resulting output

Okay, I see that this code was already fixed recently, and I just needed to confirm that you were running something earlier.  If you could, please upgrade to 1.4.21-rc1 and see if you're still getting this crash.

I've installed 1.4.21-rc1 and it seems to be working. I've to test it throughly.

Already fixed, as confirmed by reporter.
