Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |DUPLICATE --- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- The noexcept condition is evaluated too early, before the class is complete, so the third overload of fast is not considered. The out-of-class definition sees all three overloads, so gets a different result. This is a duplicate of Bug 66256. *** This bug has been marked as a duplicate of bug 66256 ***
