Bug ID: 105967
Summary: Forming a pointer to ref-qualified member function
using a function typedef ignores the qualifier
Product: gcc
Version: 12.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: iamsupermouse at mail dot ru
Target Milestone: ---
Consider following code:
#include <type_traits>
struct A {};
using F = void() &;
static_assert(std::is_same_v<F A::*, void(A::*)() &>);
GCC fails the static_assert, while Clang and MSVC accept it.
Apparently `F A::*` becomes `void(A::*)()`, without `&`. Same happens for `&&`.

That is GCC correctly rejects: using F = void() &; F t; ^ permalink raw reply [flat|nested] 3+ messages in thread
