Summary: Abort by memory allocator, possibly in
moh_files_generator
Description:
I have a server running with Asterisk 1.4.24.1 where it randomly segfault
for "unknown" reason.
I'm not sure if this is related to moh_files_generator function or with
filestream_descructor.
Let me know what needed in order to fix this crash, if GDB traces aren't
enough.
Asterisk is compiled with DONT_OPTIMIZE and others flag needed for "gdb".

I'm having the same segfaults described here. Always one of this two
backtraces:
First box:
Core was generated by `/usr/sbin/asterisk -f -vvvg -c'.
Program terminated with signal 6, Aborted.
