re PR tree-optimization/33856 (Segfault in create_data_ref/compute_data_dependences_for_loop)
PR tree-optimization/33856
* tree-data-ref.c (get_references_in_stmt): Don't add
REFERENCE_CLASS_P trees to references vector if get_base_address
returns NULL on them.
* gcc.c-torture/compile/20071027-1.c: New test.
