--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  Looks like middle-end or RTL:

  __int128 unsigned a.0_1;
  long long unsigned int _2;
  __int128 unsigned _13;
...
  a_10 = 5;
  a.0_1 = a_10;
  _2 = (long long unsigned int) a.0_1;
  _13 = _2 w* 18446744073709551615;
  _7 = COMPLEX_EXPR <_13, 0>;
  _3 = REALPART_EXPR <_7>;
