Asterisk crashes occasionally after hangup

I use debian 8.4 i386 on VM
I have build latest asterisk 13.9.1 from source.
I also use FreePBX 13.0.137.
I use latest unixODBC (2.3.4) and mysql odbc connector (5.3.6)

Problem is, that some times it crashes. It can happen about 10 times in day.
It crashes always after hangup.

I recompiled asterisk with DONT OPTIMIZE and BETTER BACKTRACES.

backtrace is on paste bin:

This appears to be a result of the UnixODBC work that was done. Asterisk 13.10 should fix this issue[1].

Thank you. I will wait for it.
But does version 13.1 certified have this problem?

No, the UnixODBC changes were added to 13.8 and did not appear in Certified 13.1.

Thank you very much! I will try to run certified version then. Hope it works well!
