Summary0002483: Eprover in Frama-C 20 beta
DescriptionI played a bit with various automatic provers in the beta

alt-ergo (2.3.0), native:alt-ergo (2.3.0), cvc4 (1.6), cvc3 (2.4.1), z3 (4.8.6) are recognized.
Eprover (2.4), on the other hand, is not recognized.

To be honest, Eprover is not such a great prover, but it has helped us discovering inconsistencies in our specifications.
Is there a specific reason, Eprover is not supported?

Attached is the error message.
