Hi there

I have an application which creates an AUGraph consisting of a DLS node connected to a mixer connected to an output node. This ran find on 10.3 and 10.4. I'm now finding, however, that it crashes Leopard at AUMixerEntry. Any thoughts?

Here's the code (updated for 10.5 APIs):

error = AUGraphNodeInfo(gAUGraph, gPianoNode,NULL, &synthUnit);
error = AudioUnitSetProperty (synthUnit, kMusicDeviceProperty_SoundBankFSRef, kAudioUnitScope_Global, 0, &outFSRef, sizeof (FSRef));

Here's the stack trace:
