            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.

--- Comment #2 from Fedor Chelnokov <fchelnokov at gmail dot com> ---
I believe PR 97934 is not much related, since the code there is processed the
same by all compilers. And here GCC is the only one showing the error.
