Oh - I see...
The common cause of crashing here area due to the converter being
reset (or even disposed) on one thread while it is rendering on another.
So you have to make sure your code is aware of the fact (and possibly
introduce a mutex) that the converter can be rendering when you want
to do a Reset (AudioConverterReset).

Bill,
I suspect that this problem lies in the fact that I have a feeder
and a consumer thread using these buffers (as you could tell from
the stack trace). I am quite sure the problem is in my code, and
wondered under what conditions the scenario below could happen.
That being said, if you still feel that there might be a bug to
address, I will happily file one.
Thanks,

Hi,
I get the following crash every once in a while trying to play
back 24 bit audio files using my own framework. I have double,
and triple checked that the buffers are the right size, and that
I don't deallocate any of them while they're in use.
Does anyone know what the problem may be?
Thanking you in advance,
\tommy
