Summary:                    Asterisk Crash after SIP Transfer
Description: 
Asterisk crashes without any error, the last two lines of log before crash
are: 
VERBOSE[2998] logger.c:     -- SIP/8083-08e16f60 is ringing
DEBUG[1891] chan_sip.c: SIP transfer: Succeeded to masquerade channels.

Similar error was reported in the following thread:
https://issues.asterisk.org/bug_view_advanced_page.php?bug_id=13256#93893

but it is closed. This happened to me twice today, but it works fine for
the last one week. I couldn't reproduce the crash.

Sorry, I didn't get a chance to recompile asterisk yet, because my server
is already in use. Here is the log of yesterday when the server stopped
again:

Succeeded to masquerade channels." message.
