I noticed we've fixed this DR already. It added [conv.prom]/4 and type_promotes_to implements it: /* ISO C++17, 7.6/4. A prvalue of an unscoped enumeration type whose underlying type is fixed (10.2) can be converted to a prvalue of its underlying type. Moreover, if integral promotion can be applied to its underlying type, a prvalue of an unscoped enumeration type whose underlying type is fixed can also be converted to a prvalue of the promoted underlying type. */ Tested on x86_64-linux, applying to trunk. 2019-10-08 Marek Polacek <polacek@redhat.com> DR 685 - Integral promotion of enum ignores fixed underlying type. * g++.dg/cpp0x/scoped_enum9.C: New test.
