While doing unrelated bisecting, I have tracked down the actual source of the
issue to c74e6f7cfd7a741fc0477fe3660eec57581b22c5 with significant confidence. 

It worked fine in gcc11 when the code checked for is_friend, and does not in
gcc12 when it checks for hiding, and thats the only part of that code that
changed between 11 and 12.
