The Plugin Host does crash at "processor->process (data);", but nothing's jumping out in the JUCE code for me right now. Seems like you would need to get in touch with FabFilter and see if they could debug; maybe they can offer some clues.

From the fabfilter guys:
When Pro-Q 2 receives a MIDI message in the processor, it notifies the controller by sending a parameter change via the host.
It does so by calling data.outputParameterChanges -> addParameterData() to create a new parameter queue if needed, and then it calls addPoint() on the queue.

I'm on call right now, so have a bit of time on my hands while waiting. I managed to test a slew of other plugins against the new code, and haven't found any issues. But, of the many plugins I have installed, very few make use of the ParameterChangeList in the JUCE Plugin Host.

Jules or Dave; I think the only thing left to do to sanity-check this code is to load up a VST3 in Tracktion, and get some automation going with it.

Dave pointed out that the implementation you posted isn't thread-safe, and these change events will be coming both from the audio thread and the GUI thread. So once I get some time to add some kind of locking, I'll post the results..
