------------------------------------

    Assignee: Sébastien Couture
      Status: Waiting for Feedback  (was: Triage)

The crash looks different than the one in ASTERISK-21775.

The segfault happens in free. There is likely memory corruption.

Please follow the instructions on https://wiki.asterisk.org/wiki/display/AST/Valgrind and provide Valgrind debug.

Get an Asterisk log leading up to the crash if possible. (with VERBOSE and DEBUG turned up to 5)

Attach it to the issue and hit Send Back when you've got those items.

> We've had Asterisk segfault with an error in res_musiconhold.c; more specifically in the 'moh_scan_files' function (line 1066):
> {code}
> for (i = 0; i < class->total_files; i++)
>   ast_free(class->filearray[i]);
> {code}
> I've attached a backtrace of the core dump. I'm wondering if this could be related to ASTERISK-21775. I haven't yet tried the patch mentioned in that issue.
