--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note MSVC has the same behavior as GCC here: ``` <source>(13): error C2244: 'Job::create': unable to match function definition to an existing declaration <source>(13): note: see declaration of 'Job::create' <source>(13): note: definition <source>(13): note: 'void Job::create(Ref<true>)' <source>(13): note: existing declarations <source>(13): note: 'void Job::create(Ref<GPU>)' ``` This is most likely related to https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p1787r6.html paper.
