I opened a PR, but am running into another issue with the [JUCE VST3 demos segfaulting on all platforms after updating pluginval to latest develop](https://github.com/Tracktion/pluginval/actions/runs/4197825567/jobs/7280658568#step:15:313).

@reuk I couldn’t reproduce locally on my own plugins, but after building the JUCE demos and running them through pluginval, I saw EXC\_BAD\_ACCESS in `getVst3SpeakerArrangement`, specifically on `BigInteger::isNegative()` inside the `std::find_if` — maybe related to [this recent commit](https://github.com/juce-framework/JUCE/commit/4b222427f9437358a82a25d40b9b135511e69462)?

On the pluginval side, it’s coming from the `supportedLayoutsWithNamedChannels` call inside `listBuses(false)`: [pluginval/BusTests.cpp at 8756d8426529305f1efa5c653fb4688b2edd3d2a · Tracktion/pluginval · GitHub](https://github.com/Tracktion/pluginval/blob/8756d8426529305f1efa5c653fb4688b2edd3d2a/Source/tests/BusTests.cpp#L34) — happy to make any changes there if you see something that’s off!
