Joshua Colp commented on ASTERISK-26852:
----------------------------------------

Your backtrace appears to contain a memory corruption. We need one or both of the following items to continue investigation of the issue:
1. Valgrind output. See https://wiki.asterisk.org/wiki/display/AST/Valgrind for instructions on how to use Valgrind with Asterisk.
2. MALLOC_DEBUG output. See https://wiki.asterisk.org/wiki/display/AST/MALLOC_DEBUG+Compiler+Flag for instructions on how to use the MALLOC_DEBUG option.

Note that MALLOC_DEBUG and Valgrind are mutually exclusive options. Valgrind output is preferable, but will be more system resource intensive and may be difficult to get on a production system. In such a case, you may have better luck getting the necessary output from MALLOC_DEBUG.
