--- Comment #5 from Arthur O'Dwyer <arthur.j.odwyer at gmail dot com> ---
Is mine the same bug? Mine is also a regression (trunk crashes where GCC 10.2
had succeeded).

// https://godbolt.org/z/Ysh6as
struct C { void f(auto) noexcept; };
void C::f(auto) noexcept(C::x) {}

Compile with -std=c++20:


<source>:3:29: error: 'x' is not a member of 'C'
    3 | void C::f(auto) noexcept(C::x) {}
      |                             ^
