Summary0005024: crash triggered by MIDI feedback and on-the-fly note addition
DescriptionThis is how to trigger an assertion:

1. create a new session with default settings
2. add a MIDI track
3. make a feedback connection with QJackCtl from MIDI 1/midi_out 1 to MIDI 1/midi_in 1
3. start recording into the new track
4. try to draw a MIDI note into the region being created (it won't persist)
5. stop the transport

ardour-3.0: /usr/include/boost/smart_ptr/shared_ptr.hpp:424: T* boost::shared_ptr<T>::operator->() const [with T = const ARDOUR::MidiSource]: Assertion `px != 0' failed.

Program received signal SIGABRT, Aborted.
