----------------------------------

Thank you!  Will test as soon as I can.  I haven't noticed any performance issues with MALLOC_DEBUG so I just keep it on.

> Hello,
>   There appears to be a memory leak in frame.c.
> Sometimes I received these errors in my logs:
> [Nov  5 21:14:49] WARNING[14918][C-00028a27]: file.c:258 ast_writestream: Translated frame write failed
> I believe this happenes because of some issues between my carrier and the asterisk system and most of the time these errors are not frequent.
> However sometimes these errors are produced thousands of times per day and when that happens the memory usage for asterisk shoots up and never recovers:
