           Summary: -Warray-bounds is not emitted inside class method
           Product: gcc
           Version: 13.2.1
            Status: UNCONFIRMED
          Severity: normal

No warning -Warray-bounds is shown when code is inside class method, defined
inside the class body or outside if they are inline or constexpr.

struct S{
    int p(){
        int x[2] =3D {0, 0};

        return x[3]; // no warning shown
    }

    static int ps(){
        int x[2] =3D {0, 0};

        return x[3]; // no warning shown
    }

    int ps2inl();
    int ps2();
};

inline int S::ps2inl(){
    int x[2] =3D {0, 0};

    return x[3]; // no warning shown
}

int S::ps2(){
    int x[2] =3D {0, 0};

    return x[3]; // warning shown correctly
}

int f(){
    int x[2] =3D {0, 0};

    return x[3]; // warning shown correctly
}
