That's rather worrying. I have several apps with virtually identical
code. I think I got it originally from Technical Note TN2091.

Sorry, the crash reports don't make that obvious
Crash report excised, see previous message in this thread.

Hello,
Recently, in a well-established product where this piece of code
hasn't changed for ages, the following assert has started triggering
on some customer machines:
// Create AUHAL
AudioComponentDescription desc = { 0 };
desc.componentType = kAudioUnitType_Output;
desc.componentSubType = kAudioUnitSubType_HALOutput;
desc.componentManufacturer = kAudioUnitManufacturer_Apple;
desc.componentFlags = 0;
desc.componentFlagsMask = 0;
AudioComponent comp = AudioComponentFindNext (NULL, &desc);
assert (comp);
This only seems to happen on 10.13.3 and doesn't seem to be caused by
any rogue third-party plugins. A sample crash report is included below.
I'd really like to know how to fix this - the number of complaints is
growing and it's a showstopper. Resetting the PRAM and SMC doesn't help.
Many thanks - Paul Sanders.
