Update: Only *seems* to happen in the sandboxed (App Store) version.  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.
