--- Comment #2 from m.cencora at gmail dot com --- So I guess this falls into the "confusing overload resolution for user-defined conversion" but I fail to see what can be confusing here. createInt() returns prvalue, so later it binds to xvalue for the purpose of implicit conversion operator invocation. That means that r-value qualified conversion operator is chosen. If your advice is to avoid using "-Wconversion" that it is rather unfortunate because user looses good warnings (e.g. about conversions that may alter the value). Also there is no way to silence the warning for such a code, since gcc warns on each call-site, not on definition-site of the overloads. So it either unfeasible or even impossible if the definitions are in library code, but warnings are enabled in user code. Please consider removing the warning generation in such scenarios.
