I don't think so.  In any case, it shows also up for C
if one uses the nested-functions extension:


int
main ()
{
  int i, j;
  void bar()
  {
    #pragma omp for simd collapse(2)
     for (i =3D 1; i <=3D 16; i++)
       for (j =3D 1; j <=3D 16; j++)  /* Note: *no* non-rectangular loop ne=
st.  */
         ;
  }
  bar ();
  return 0;
}


(I get an ICE since GCC 8 and none with GCC 7; thus, I might be a regressio=
n,
but I have not checked in depth.)=
