--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
ICEs since r15-975-g2fb9363dc3596cd7fda90a8c816d7e27dd9e085b when the option
has been introduced.

Testcase with _BitInt to simplify the constant creation:
int s;

void
foo ()
{
  s /= ((__int128)0x33333333333333333333333333333333uwb) + 1i;
}
