I think I found the problematic commit:

18619da58c77461642c36cee9f0463c968877f75 is the first bad commit

        * call.c (add_function_candidate): Take the address of 'this' here.
        (build_over_call): And here.
        (build_new_method_call_1, build_op_call_1): Not here.
        (build_user_type_conversion_1): Or here.
