--- 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>;
