Hi,
I am experiences MIDI crashes with virtual CoreMIDI destinations. The crash happening randomly, without sending any MIDI messages to the destinations. What I found also the crash is only happening when there are other MIDI sources too - like IAC or a hardware MIDI controller - and I use team (so an input port have been created for them).
There crash always looks like this, and the same code works on 10.8 and later:
