Hi everyone, update here.
I contacted Argyll and Graeme Gill helped me. He had to send me a debug version of dispread in order to get me going for now – supposedly it’s a temporary fix. Here are his words:
“that’s good to get you going, but the problem isn’t actually fixed – it’s
just hiding somewhere else because I added some debug code.
Hard to know if it’s a latent bug in my code, or an issue with
rosetta translating between x86 and ARM, since it doesn’t
seem to show up when run on native x86 HW.
I’ll leave the code in that recognizes the specific crash
you had for future ArgyllCMS releases, but it is likely just a short
term workaround.”
