I don't have access to these plugins myself and I can't find any old backtraces, but from what I remember the segfault happened in mscvrt. This issue applies to all Applied Acoustics Systems plugins and the segfault occurs when the plugin shuts down (in `effClose()` for VST2 plugins and I think the VST3 version did the same thing in a call to the edit controller's `IPluginBase::terminate()`. This happens when using these plugins under yabridge or under any normal Windows VST2 or VST3 host.
Thank you for adding more details!
