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!
