All,

Has anyone seen this before? This appears to be a Swift or app_swift bug. I'm having a difficult time finding any information or support on this.

Asterisk version:
Asterisk 11.6-cert4 built by asterisk @ ivrd02 on a x86_64 running Linux on 2014-08-11 13:55:25 UTC
OS:
Linux livrp03 2.6.32-431.11.2.el6.x86_64 #1 SMP Mon Mar 3 13:32:45 EST 2014 x86_64 x86_64 x86_64 GNU/Linux

When Asterisk crashes, the backtrace always looks something like the following:

The "out of bounds" line looks like it may be pointing to the issue.

argv = {0x0, 0xffffffffffffb9b0 <Address 0xffffffffffffb9b0 out of bounds>, 0x0}

Should I look into using another TTS engine?

Hi Bryan,

Do you or anyone have any experience using Swift with UniMRCP? I tried a
few months ago but gave up. The documentation is not very clear.

Yes, I am reaching out to the developer of app_swift.

thanks,

Bryan Burroughs
