#4  0x0000000001250010 in vrp_prop::check_mem_ref (this=0x7fffffffced0,
location=102528417, ref=
    <mem_ref 0x7fffefdb38c0>, ignore_off_by_one=false) at
/home/marek/src/gcc/gcc/tree-vrp.c:5097
5097          arrbounds[1] = wi::to_offset (TYPE_SIZE_UNIT (reftype));

here reftype is "const void" so taking its size is wrong.
