Florian Weimer <fw at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #2 from Florian Weimer <fw at gcc dot gnu.org> --- I was wrong, conversions from int to bool are supposed to be narrowing, and Two + 1 has type int, and getting from there to bool is not permitted in a converted constant expression. I still have some concerns about narrowing conversions to bool, but those are independent of the enum issue.
