****** ADDITIONAL INFORMATION ******
The asterisk version I'm using is r209515 from the 1.6.1 branch. I did not use the 22.214.171.124 version (which was the newest when I set up the system), because I needed the T.38 fixes which went in just after 126.96.36.199 was released. If necessary, I can recompile 188.8.131.52 and try to reproduce. But that would be quite some effort on the production system, especially as the segfault is not reproducible every time.

I'll acknowledge this for now, although it may be beneficial to reproduce this on a newer version, but I have a feeling this is probably the same on a newer version as I don't remember any issues like this one. I'll take a look though and see if anything might be related.

It would still be nice to confirm this is an issue under the latest version. Can you please do so and report back?

I'm sorry lmadsen, but I have not encountered this segfault again, although the asterisk version I'm using is still the same.

I'm going to close this for now, but if you end up getting this again, please re-open the issue and we can take it from there. Ideally you'll have a backtrace on a newer version of Asterisk with DONT_OPTIMIZE enabled in menuselect.
