            Bug ID: 108559
           Summary: A new crash with using a simple class, inheritance and
                    a function
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zakkariusr at gmail dot com
  Target Milestone: ---

The following code:

struct A {
    int g = 0;

    A() {}
    A(const A&) {}
};

struct B : A {};

A u() { return A{}; }

int bug() { return B{u()}.g; }

int main() {
    return 0;
}

causes a compiler crash on the current gcc(trunk) 13.0
