Summary0009214: Ardour crashing when stopping the recording
DescriptionI record a few tracks and all of a sudden at the end of a recording it crashes and leaves me without my last take.
It has been an issue with all of the ardour versions I used (since at lease 5).
I am using qjackctl as the jack driver.
also having some vsts like pianoteq and drumgizmo.
Steps To Reproduceopen a new session, start recording (audio or midi doesn't matter) give it a nice 5 min track. open a new track and record till you find the perfect take, then it will crash leaving you without that awesome take you did.
that's pretty much it.
Additional InformationI followed the instructions about getting the debug errors, I hope it helps
Tags7.2, Butler drops pool trash, crash, Graph::drop_threads(), recording
