Does anybody understand this failure of isatest? The process is terminated after many hours.

I've tried to reproduce it by hand, loading Codegenerator_Test/Generate.thy into HOL-Library. It works for polyml-5.4.1_x86_64-darwin and polyml-5.4.1_x86-darwin, but polyml-5.3.0_x86-darwin does not seem to terminate.

Any ideas?
