--- Comment #13 from markeggleston at gcc dot gnu.org ---
The test case in comment 0 is fixed by:

trans-array.c

@ -3638,8 +3638,11 @@ gfc_conv_array_ref (gfc_se * se, gfc_array_ref * ar,
gfc_expr *expr,
   /* Handle scalarized references separately.  */
   if (ar->type !=3D AR_ELEMENT)
     {
-      gfc_conv_scalarized_array_ref (se, ar);
-      gfc_advance_se_ss_chain (se);
+      if (se->ss)
+       {
+         gfc_conv_scalarized_array_ref (se, ar);
+         gfc_advance_se_ss_chain (se);
+       }
       return;
     }

make -j 8 check-fortran does not produce any additional test case failures =
on
x86_64.

The test case in comment 7 still produces the same ICE.=
