Richard Mudgett commented on ASTERISK-21895:
--------------------------------------------

Your backtrace appears to contain memory corruption and we require valgrind output in order to move this issue forward. Please see https://wiki.asterisk.org/wiki/display/AST/Valgrind for more information about how to produce debugging information. Thanks!

Since you are using at least v1.8.20, you can also use MALLOC_DEBUG as a poor man's substitute with less performance loss.  Also you almost always need to compile with DONT_OPTIMIZE for any backtrace to be useful.

Do you know how to reproduce this problem?
