            Bug ID: 102201
           Summary: Accepts invalid C++98 with nested class and sizeof of
                    outer's non-static field
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: accepts-invalid
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Take:
struct outer {
    struct inner {
         inner() :x(sizeof(y)) { }
        unsigned int x;
    };
    int y;
};

----- CUT ----
The above code is valid C++11 but invalid C++98 because the field y is
non-static.
