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".

---------------------------------------------------------------------- 
My valgrind ran for two days with several reported memory errors in file. 
Except that additional flags were needed to make the file more useful.

I restarted asterisk with valgrind again and it crashed before beginning
call processing.  To be honest I don't know if it is common for Asterisk to
crash while starting under Valgrind.  So I am posting the full valgrind
output with all required flags "valgrindcrashg07022009allflags.txt"

Next I started valgrind again with all required flags and I will allow
this to run for several hours and will upload that valgrind file later. 
This I hope will allow a developer to see where the memory issues are and
will get us a patch(es).
I don't expect anything to crash under valgrind since I expect this is a
race condition in Asterisk that will not appear when running under
Valgrind...
