12 years ago In fact, loading a session that uses HL LV2 doesn't crash OOM - the plugin just doesn't produce any sound as if its failed to load its chunk data or something properly and OOM gives an error like:
Application asked to unregister timer 0x1c000029 which is not registered in this thread. Fix application.
Running the latest debug builds of OOM and DISTRHO (as of 19th May) under AV Linux 5.0.3, OOM crashes when I attempt to load a project that uses the HighLife plugin, in both its VST and LV2 versions and built with or without debug.
Here is a backtrace from trying to load a session which uses the latest debug-built Highlife VST plugin:
