Topic: Timeout proof of False in empty file (2023 RC3)

I'm getting timing out proofs of False in an empty Scratch.thy file with RC3 from vampire. Is this expected behaviour? I can't reproduce in 2022.

This indicates that vampire has a bug

@Martin Desharnais I don't remember, was there a vampire update between Isabelle2022 and Isabelle2023-RC3?

As we do not follow vampire releases regularly, it might a bug in an old version

As a work around, you can remove vampire from the list of provers

Not sure if relevant but Makarius mentions a "Last-minute improvement of Sledgehammer for vampire.", so maybe that :shrug:

Yes, I started using RC4 and the problem has not recurred :)
