UPDATE: thanks to @Jens.Peter.Nielsen for the confirmation.
I’ve been noticing a segfault in Rack (2.0.6) when closing after having done some copy-pasting of modules during the session. I don’t know the exact reproducibility of this yet, so I want to try first with someone using a similar setup: using/compiling Rack sources in Windows in the MINGW64 shell.
If the bug (and the fix I’m proposing) are confirmed also on someone else’s setup, then I will submit this to VCV support. Please direct-message me if you are interested in helping me confirm this.
