I see such crashes in users crash reports, but I can't reproduce it locally and provide any example for simple reproduction.

Similar crashes (with CrashIfClientProvidedBogusAudioBufferList in the stack) I also saw before with Qt 5 , so probably this is some old issue.
Also it seems doesn't depend on macOS version or Mac model, see Environment.
