    * c-ubsan.c (ubsan_maybe_instrument_reference_or_call): Change type
    argument to ptype, set type to TREE_TYPE (ptype).  Don't call
    get_pointer_alignment for non-pointers.  Use ptype, or if it is
    reference type, corresponding pointer type, as type of kind
    argument.
    (ubsan_maybe_instrument_reference,
    ubsan_maybe_instrument_member_call): Adjust callers.

    * g++.dg/ubsan/pr63813.C: New test.
