Summary0004158: Crash after deleting and re-adding a synth plugin to a MIDI track that also has a bus send on it
DescriptionI've created a MIDI track and added a synth to it, and then added a send off to a bus; this all works just as you'd expect. However, if I delete the synth plugin, add a new one, and then drag it to the top of the plugin list, Ardour crashes.

Steps to reproduce:
1) Create an aux bus
2) Create a MIDI track
3) Add a synth plugin to the MIDI track
4) Add an aux send to your bus on the MIDI track
5) Delete the synth plugin
6) Add another synth plugin
7) Drag the synth plugin to the top of the track's plugin list

Ardour will crash at this point.

I tried to replicate this behaviour with an effect plugin on the MIDI track, instead of the send. In this case, Ardour refuses to let you delete the synth plugin until the effect plugin has been deleted, presumably to prevent the track's plugin list getting in to an odd state. It doesn't pop up any warnings about this, though -- it just refuses to perform the deletion -- which is probably a bug in itself.

i replicated these steps using a mono aux bus, and ardour did not crash. a more precise recipe appears necessary.

alternatively, a backtrace might be enough to make some progress.

I did some more testing on this, and the cause seems to be using a synth plugin with stereo output. I had tried two different plugins to make sure it wasn't a plugin-specific issue (Calf Monosynth and Linuxsampler), but both of them happened to be stereo. Retesting with "qin", a simple synth with only a mono output, Ardour did not crash.

The channel count of the bus doesn't seem to matter. I had been using a stereo bus, but both stereo and mono busses either work (with the "qin" synth) or fail (with Calf Monosynth and Linuxsampler).

I've attached a backtrace. I also receive this error message after the crash:

ardour-3.0: ../libs/ardour/panner_shell.cc:272: void ARDOUR::PannerShell::run(ARDOUR::BufferSet&, ARDOUR::BufferSet&, ARDOUR::framepos_t, ARDOUR::framepos_t, ARDOUR::pframes_t): Assertion `inbufs.count().n_audio() == 0' failed.
Aborted

Forgot to mention that I'm running Calf from git, in case that's relevant:

Should be fixed in SVN 9845.
