--- Comment #4 from Christoph Reiter <reiter.christoph at gmail dot com> --- I see, thanks for having a look :) We do have some open bugs re broken exception handling with mingw32, like https://github.com/msys2/MINGW-packages/issues/9289#issuecomment-945306860 Sadly no one stepped up to look into that. Do you think this could be related?
