@CohenCyril it might be the same issue as this (minimized) example: proux01@4491d95 |

I don't think so, because the error message is different: but it could still be the same error in a different disguise. I'll try to minimize later... |

Do you get the anomaly while running HB, or it is plain Coq? |

If I replace the failing line HB.instance Definition _ (C : ConcretePreCat.type) := PreFunctor_IsFunctor.Build C U concrete (@concrete1 _) (@concrete_comp _).with Definition mixin (C : ConcretePreCat.type) := PreFunctor_IsFunctor.Build C U concrete (@concrete1 _) (@concrete_comp _).
HB.instance Definition _ (C : ConcretePreCat.type) := mixin C.the error is on the first line, so in plain Coq but using a HB generated constant? |
