if you are using Freepbx, why are you reporting a bug on the Asterisk bug-tracker? Please don't open bug reports here unless you are using Asterisk.
By: Martin Dachselt (mada123) 2006-09-13 10:40:49

Sorry, it seems i wasnt clear.
We are using asterisk 1.2.12.
I just mentioned freebpx because this is the frontend we are using.
By: Serge Vecher (serge-v) 2006-09-13 12:30:07

Ok, thanks for clarification. Was Asterisk compiled with "make dont-optimize". If not, please recompile and redo the backtrace.
By: Martin Dachselt (mada123) 2006-09-14 14:23:35

as requested i rebuilded asterisk with "dont-optimize".
ASterisk crashed today one time with the exception:

does this patch resolve the crash?
By: Joshua C. Colp (jcolp) 2006-11-15 16:34:57.000-0600

Fixed in 1.2 as of revision 47711, 1.4 as of revision 47712, and trunk as of revision 47713. It's a modified fix from the patch as it's not possible for fixup to be called without valid channels.
