Steps To ReproduceNot sure how this would be reproduce-able on different setups than mine. Every time when crashing happened I was usually just playing my MIDI connected keyboards while my certain project was open. Segmentation fault often occurred during playback but not always. I had some other software open too but none of them had issues during Ardour's crash.

That backtrace there is from a debug-build with line numbers.
