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".

aragon, thanks for the feedback!

coolmig, you are correct that most of the backtraces are related to files
mode MoH.  The valgrind output on this bug from aragon is what pointed me
to the problems addressed by the last fix.  It's possible that the same
problem could cause corruption in res_musiconhold if any non-files mode MoH
classes were configured.  If you _only_ have files mode configured, then
it's unlikely that the last patch will change anything.

Testing is still certainly appreciated.  However, I'll still be thinking
and looking for what else could cause these crashes.
