This code is provided by people in the QT Group - you might want to
ask them (QT API)
You can also validate the AUs you are using - run the auval tool on
these. If these AUs pass or fail validation would be interesting to
know.
You can also host these AUs in the AU Lab application (/Developer/
Applications/Audio/) - you can bring up either their custom or show
their generic views. If the AUs have expert parameters, then you'll
see a disclosure triangle that when expanded, will show the expert
params. (Oh, expert params are params that are marked with the
"expert" flag - so they should not normally be presented to users)

I looked at this a bit with F8. The crash with F8 occurs at line
1898 of SGAudioSettings.mm "[auview setShowsExpertParameters:YES];"
What does setShowsExpertParameters turn on? If I comment out this
line and then load F8, it doesn't crash. But, the GenericView
shows a random subset of the F8 parameters when it is loaded.
If someone can point me at documentation for AUGenericView, perhaps
I can figure out what parameter information F8 is providing that is
instigating the crash.

Hi,
I have noticed that some 3rd party AudioUnits crash the WhackedTV
sample code. I also noticed the same thing with my application
which uses AU's in a similar manner (though I didn't base my code
on WhackedTV), which is that it uses the AUGenericView.
I filed a bug, but I'm wondering if this is a problem with
WhackedTV's (and my) implementation, or a bug in the system, or a
bug in the AU that only shows up when used in this manner. Some
AU's I've noticed this with are:
iZotope: Vinyl
MusicUnfolding: F8
DestroyFX: Transverb
All crash on different methods, but both F8 and Vinyl crash during
AUGenericView methods. Transverb crashes on an internal method.
Thanks.
