Summary:                    Segmentation Fault with 1.4.21.2 in rtp.c:1131,
Application chanSpy
Description: 
i do have encountered a segmentation fault on a 1.4.21.2 machine while 
using the ChanSpy Application - i have tried to reproduce the segfault - 
but without success.

I think the segfault is because of two different sip users where trying 
to start ChanSpy on the same channel - but i don't know exactly...

I am running asterisk with optimized code - so the backtrace isn't as 
usefull as it could be - if i am able to reproduze the fault - then i 
will run it on a non optimized version to produce a more useable 
backtrace (how much does it really costs to disable the optimizations - 
will it be a problem on a production machine running at loadavg around 
1, cpu utilization around 30 % ?)

This issue appears to be similar to issue
http://bugs.digium.com/view.php?id=13682, so I'm going to mark them
related.

One thing that I think will be helpful is to get valgrind output when this
problem occurs. For instructions on how to use valgrind with Asterisk, see
doc/valgrind.txt in the Asterisk source directory.

For the load you are talking about, turning off optimizations should not
make a huge difference in performance. Running valgrind, on the other hand,
will cause noticeable slowdown, and so you may want to try a test run with
valgrind before launching it on a production system.
