Bug ID: 102465
Summary: Inaccessible operator == breaks child class with
spaceship operator
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: fchelnokov at gmail dot com
Target Milestone: ---
Below code is valid:
```
#include <compare>
struct A {
std::strong_ordering operator <=>(const A &) const = default;
bool operator==(int) const;
};
struct B : A {
virtual std::strong_ordering operator <=>(const B &) const noexcept =
default;
};
B b; //GCC error here
```
but GCC prints an error compiling it. Demo: https://gcc.godbolt.org/z/584nhfxxs
It shall just delete `operator ==` in B.
