Yes we can reproduce this crash scenario by running calls between portsip and
Xlite soft phones. The issue we have observed is CODEC translation between iLBC
and alaw with following warning messages,

We can reproduce the problem as below,
1. Call between Xlite(iLBC) to portsip(G711), RTP through asterisk.
2. portsip attended transfer the call to another portsip client
3. on complete transfer asterisk crashes (then started by safe_asterisk) with
above warning.
FYI, we have not installed asterisk with iLBC support.
We will try to upgrade asterisk and try to reproduce this scenario.

That is quite old. Lots of bugs (and several security issues) have
been fixed since then. Try the latest in the 1.8 branch.
For the crash , follow the instructions here
https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace
and gather a backtrace after recompiling with the required options.
(preferably after upgrading to the latest 1.8, as there may have been
improvmen

These messages alone don't show the whole picture.
https://wiki.asterisk.org/wiki/display/AST/Collecting+Debug+Information
Collect a log with VERBOSE and DEBUG turned up to level 5, SIP debug
turned on, and pastebin that.
I'd wait until after you test with the latest in 1.8
