[Bug fortran/21063] ICE in gfc_conv_ss_descriptor, at fortran/trans-array.c:1224 after using maxloc function

We die while looking for an array descriptor for the vector subscript: 
  /* For vector array subscripts we want the size of the vector.  */ 
  vecss = ss; 
  while (vecss->data.info.ref->u.ar.dimen_type[dim] == DIMEN_VECTOR) 
    { 
      vecss = vecss->data.info.subscript[dim]; 
      gcc_assert (vecss && vecss->type == GFC_SS_VECTOR); 
      /* Get the descriptors for the vector subscripts as well.  */ 
      if (!vecss->data.info.descriptor) 
        gfc_conv_ss_descriptor (&loop->pre, vecss, !loop->array_parameter); 
      dim = vecss->data.info.dim[0]; 
    } 
 
But gfc_conv_ss_descriptor starts with: 
static void 
gfc_conv_ss_descriptor (stmtblock_t * block, gfc_ss * ss, int base) 
{ 
  gfc_se se; 
  tree tmp; 
 
  /* Get the descriptor for the array to be scalarized.  */ 
  gcc_assert (ss->expr->expr_type == EXPR_VARIABLE); 
  gfc_init_se (&se, NULL); 
 
That assert triggers.  For my small test case, the expr_type is EXPR_ARRAY 
and for the maxloc test case it is EXPR_FUNCTION.
