Is anyone familiar with the error message:

Malformed global fact "Set_Proc.open_branch.lemma_3_1"⌂
Illegal fixed variable: "'a"

Even for

lemma foo: "True" by auto

I get this error message. The message occurs as soon as I give the lemma a name.

The problem occurs only after a sublocale in the locale open_branch.

Ah, I tracked down the error. It was because I didn't fully instantiate the sublocale (one argument was missing).

Thanks, that helped me solving the same issue!
