        * tree-ssa.c (useless_type_conversion_p): Split into a
        recursive and a non-recursive part.
        (useless_type_conversion_p_1): New function.
        * tree-ssa-ccp.c (fold_stmt_r): Make sure that the result
        from maybe_fold_offset_to_reference is trivially convertible
        to the desired type before doing the simplification.

        * gcc.c-torture/compile/pr33166.c: New testcase.
