Charlie Smurthwaite updated ASTERISK-25436:
-------------------------------------------

    Description: 
I observed several crashes under asterisk 13.2. I did not record significant details about these, but instead upgraded to 13.5.0. Today under 13.5.0 I have experienced another crash (a segfault). The following is observed in the log immediately before the crash:

{code:title=Asterisk Log|borderStyle=solid}
[2015-09-30 13:43:24] ERROR[6541][C-00000ee1] json.c: Error building JSON from '{s: s, s: s}': Invalid UTF-8 string.
[2015-09-30 13:43:24] ERROR[6541][C-00000ee1] stasis_channels.c: Error creating message
[2015-09-30 13:43:24] ERROR[6541][C-00000ee1] json.c: Error building JSON from '{s: s, s: s, s: s, s: i, s: i, s: i, s: o}': Invalid UTF-8 string.
{code}

I will attach a backtrace of this crash.

Another instance of this crash (under Asterisk 13.2.0) included the following log entry, suggesting (as the backtrace does) that this crash is related to fax channels:

{code:title=Asterisk Log|borderStyle=solid}
[2015-09-22 16:44:44] WARNING[2646][C-0000bddf] app_fax.c: Transmission error
{code}
