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".

Uploading valgrind output from a few hours of testing.
There is lots of good data here since all flags were enabled in Valgrind.

mmichelson can you take a look please?
there are two files uploaded of interest
valgrindcrash07022009allflags.txt (Asterisk crashed under valgrind during
reload)
valgrindnocrash07022009withflags.txt (Asterisk did not crash but core show
locks was very interesting; indicating some locking on unused PRI channel)
