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.

----

Memory corruption could be the cause that codec_opus is complaining of a corrupted stream.

ASTERISK-27238 and ASTERISK-27412 are also memory corruption issues which were recently fixed and have not gone out in a release yet.

You'll have to use valgrind since you are using codec_opus and MALLOC_DEBUG alters the allocation API to track memory.

> Latest Asterisk 15.1.4 crash when attempting to bridge audio. Don't have a repro on this one reliably.
> Interestingly, this is the dialplan we see in leading up to the crash, which doesn't on the surface seem related to the crash itself:
