--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Fixed on the trunk so far.
Guess for backports we want instead a minimal change (i.e. just the
+                        && INTEGRAL_TYPE_P (TREE_TYPE (TREE_OPERAND (op0, 0)))
and
+                        && (TYPE_PRECISION (TREE_TYPE (TREE_OPERAND (op0, 0)))
+                            < TYPE_PRECISION (type0)))
additions for C++ FE).
