How can we know? I mean, you wrote the code, so fire up the debugger
and see where the crash occurs! If that doesn't work for you, send the
user a debug version so he can send you his log file (and the call
stack with the clear text symbols).
Could it be that CoreAudio is using some proc pointer in your code
that gets free'd? This looks like a bad bad crash...

ANybody know what i might be doing wrong?
I'm using core audio to record audio and using quicktime to display a
monitor.
