junky- are you working on reproducing this one?

I've reclassified this bug, since format_mp3 is _NOT_ part of Asterisk proper, and as such does not qualify as a 'crash' bug against Asterisk. If someone can provide a patch to solve the problem we'll review it, but otherwise this will be a low-priority issue.

i'll during week-end.

Closing due to lack of patch availability. Please re-open if you have a patch to solve the problem.

I have been told that there is a known issue in the mp3 lib that this is using that certain kinds of mp3 compression will cause it to segfault. Try using sox to decode to slin and re-encode into mp3 and it should resolve this issue. Also, if you are using the mp3 for MOH, it will be much more efficient to just leave it in raw slin.
