Summary0005144: ardour 3 crash related to MIDI i/o
DescriptionFrustrated enough with unstability of 2.8 version, i decided to upgrade system to new version and compile bleeding-edge of ardour for myself.
Sadly, it crashes as well. So my bugreport follows:

How to reproduce:
1) start up a session, add some buses
2) set up a midi-in from bcr2k via jack sequencer to the ardour
3) add some LADSPA plugins, assign a midi control for some of their parameters
4) after some time of toying with controls ardour crashes. Crash also sometimes occurrs when a plugin with associated midi control is deleted.


Expected behaviour:
Ardour won't crash

There is clearly some kind of memory corruption inside:

dmesg also reports an error:
