Summary0007250: Ardour 4.7 occasionally dumps core mid-MIDI recording
DescriptionThis is the third time I have witnessed a crash while recording from my MIDI keyboard. The first time, PulseAudio was running in the background and I was getting occasional xruns. The most recent two times, PulseAudio had been killed prior to starting JACK, and no xruns occurred—just the core dump.
Steps To Reproduce1. Create a new Ardour project, using JACK
2. Create a new MIDI track. I used CALF Fluidsynth as my instrument and a2j.
3. Start recording on the MIDI track. I think it was about 7 minutes into the recording when Ardour crashed, but I have no idea of a real timeframe or if there was any consistency to the timing of previous instances of this crash.
Additional InformationI've attached the dump printed to the journal.
TagsNo tags attached.

I just reproduced this consecutively by doing the same thing over again. I noticed this before the dump in my journal from the second crash:

Feb 21 00:47:53 G73-T440p kernel: ardour-4.7.0[12273]: segfault at 736f702d657e ip 00007f50800eb1d8 sp 00007fff983c4690 error 4 in libgtkmm2ext.so.0.8.3[7f5080030000+fe000]

go to prefs and disable "Draw waveforms while recording". crash should go away.

I'll give that a try tonight, thanks. Is waveform drawing known to cause crashes when recording MIDI for more than a few minutes?

I tested Ardour without drawing waveforms during my recording and got 15 minutes in consecutively, no issues. Granted this issue was sporadic to begin with, but I hope it will not come back so long as I keep this setting. Thank you.
