interesting. i didn't realize the problem seems to specifically be the sound playback via the manager interface.
a couple weeks ago, my asterisk on my dev box crashed, i did some preliminary investigation, but since we hadn't had any problems in production or qa, i chalked it up to me messing up my dev install somehow.
anyway, here's the backtrace of the core:
(gdb) bt

#9 0x00b44341 in start_thread () from /lib/tls/libpthread.so.0
#10 0x009096fe in clone () from /lib/tls/libc.so.6
the interesting lines to me are #4 and #5:
#4 0xb7e8899b in conference_play_sound (fd=12, argc=14643636, argv=0xdfdc5c)
at cli.c:225
#5 0x0809786b in ast_cli_command (fd=12, s=0x71bfb8a6 <Address 0x71bfb8a6 out
of bounds>) at cli.c:1364
line 4 becauset the argc passed into conference_play_sound() is so large, and line 5 because there seems to be an out--of-bounds problem in the asterisk code ( i.e. before the app_conference code is called ).
based on what you said in your last post, i'm going to look at this more.
if you have any thoughts on my backtrace/analysis, let me know.

The issues with the double-free crashes that we've had all seem to be
caused by playing of audio files(like the entry/exit sounds or the
DTMF broadcast). But these functions use the app_conference code that
was already existing to play audio files from manager API commands so
the issue was there it just wasn't as tested because not many people
use the manager command a lot to play audio in conferences.
