I cannot reproduce this with trunk rev. 176000
gcc version 4.7.0 20110707
Might have been fixed or hidden by this patch:

* tree-data-ref.c (dr_address_invariant_p): Remove.
(find_data_references_in_stmt): Invariant accesses are ok now.
* tree-vect-stmts.c (vectorizable_load): Handle invariant
loads.
* tree-vect-data-refs.c (vect_analyze_data_ref_access): Allow
invariant loads.
* gcc.dg/vect/vect-121.c: New testcase.
