Summary:                    [patch] 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".

Fix memory corruption caused by format_mp3.

format_mp3 claimed that it provided AST_FRIENDLY_OFFSET in frames returned
by
read().  However, it lied.  This means that other parts of the code that
attempted to make use of the offset buffer would end up corrupting the
fields
in the ast_filestream structure.  This resulted in quite a few crashes due
to
unexpected values for fields in ast_filestream.

This patch closes out quite a few bugs.  However, some of these bugs have
been
open for a while and have been an area where more than one bug has been
discussed.  So with that said, anyone that is following one of the issues
closed here, if you still have a problem, please open a new bug report for
the
specific problem you are still having.  If you do, please ensure that the
bug
report is based on the newest version of Asterisk, and that this patch is
applied if format_mp3 is in use.  Thanks!
