Arturia's new Pigment plugin crashes with JUCE audio plugin host

The new Pigments plugin from Arturia crashes when you try to open its editor window. This is completely reproducible with the JUCE Audio Plugin Host. How can this be fixed? It’s very odd that the Arturia plugins all run perfectly fine with non-JUCE hosts but break with any JUCE host, as far as we can tell.
Help would be appreciated.

This crash is happening in Arturia’s code, so there’s nothing we can do other than send another email to their tech support to let them know about the issue which I’ll do now.

We’ve also emailed them - but I’m much more concerned as to why their plugins (and Korg Gadgets as well, it now turns out) work perfectly fine with hosts that are not JUCE based. Korg is using JUCE (it’s proudly on your discover page) and I think Arturia is as well. I realize the crashes appear in their codebase but is it possible that something is wrong with the way those plugin editors are being invoked from a JUCE host?

It’s impossible to know without having access to their code and being able to step in and see exactly where the crash occurs. Although given that there are thousands of JUCE based plug-ins out there which don’t crash or show a blank UI when using the JUCE hosting classes, and the JUCE plug-in demos using the latest code don’t either, I’d say the odds are more likely that it’s an error in their code.
