--- Comment #1 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
The problem here is that the parser builds an ARRAY_NOTATION_REF with a type of
ptrdiff for length and stride.  Later in cilkplus_extract_an_triplets we
convert convert length and stride to an integer_type_node.  This causes
create_array_refs() to use a stride of integer_type, while the start is still a
ptrdiff.
