UniMRCP seems to be causing Asterisk Signal 11 crashes

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Seems that at lease once a day a seemingly random outbound call will cause 
asterisk to sig 11.
2.  Call is a PTSN outbound call via a T1, asterisk dials, does TTS then 
crashes halfway through it.
3.  Other TTS calls work fine, load on the box is about 5 concurrent calls out 
via 1 T1.  No hung channels or anything to indicate an asterisk issue.

What version of the product are you using? On what operating system?
Asterisk 1.6.2.14 + unimrcp-1.0.0 + uni-ast-package-0.3.2 on CentOS release 5.5 
(Final) x86_64

Please provide any additional information below.

Please see attached file for the backtrace.

Hi, are you using app_unimcp.c in revision 1805?
Update it to a newer version.
See https://groups.google.com/d/topic/unimrcp/erE2eJjkpaM/discussion
You should update UniMRCP to latest svn revision too.

Looks promising as our issue, I'm running it by our Asterisk/TTS Dev to see 
which version of app_unimrcp.c we are using.

Thanks.

Well looks like the SVN version of UniMRCP tanks our asterisk install when the 
module loaded. Any ideas on why that would be?  Do we need to step up to a 
higher version of asterisk?

Below is a one-line change which fixes the problem. The problem was in the 
Sofia-SIP library which deleted a data storage key which was not created. That 
eventually made Asterisk crash because of memory corruption issues. The fix 
will be available in the upcoming release of the dependencies.
