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

Have this issues, it happens very rarely, so it's hard to reproduce. 
Asterisk 1.8.23.0
Not sure if i would be able to use high debug and verbose and valgrind on productive server. 
I have few core dumps i can attach if it would help

> 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.
