Summary0009573: Crash when loading drumkv1, samplv1
DescriptionLoading drumkv1 or samplv1 freezes Ardour.
Steps To ReproduceOpen Ardour, either add a track or add a plugin to a track, and select the drumkv1 or samplv1 plugin. Ardour should stop responding entirely at that point.
Additional InformationI'm using a self-built Ardour from the tarball at ardour.org. I have included a backtrace and the most relevant parts of the command line output. If I need to, I can upload the exact drumkv1 that is crashing. Running the standalone app or through Carla has no issues whatsoever, but for some reason loading it in Ardour just freezes it.
Tags8.2, drumkv1, plugin, samplv1
