Well I got a quick reply from Luca. He is aware of the problem; a fix for the new ipad is complete and awaiting app store approval. He's on top of it!
So no worries!

I know very well the problem.
It's bug of new Apple compiler and I submitted today a new release that
should solve this bug.
I hope they will approve and release in a week.
Sorry for the inconvenience,
Please let me know if you are satisfied of new version.
