Anyone on the CoreAudio team have any idea why this crash might be
happening?

It happens after processing audio through an audio unit (it's not
real clear which one, but it doesn't look like it's hit anything but
Apple code at this point) and it's trying to close it down and remove
it...
It starts with the "dealloc" of the AudioUnit editor wrapper, which
tries to close the component. By this time, the window (both Carbon
and it's Cocoa wrapper) enclosing it is already gone - but it looks
like the AUGenericView is trying to rebuild it.
Is this my app's fault? Why the GUI rebulding? I didn't start seeing
this crash report come from users before 10.4.7 (IIRC), it's fairly
recent.
TIA for any help.
