--- Comment #9 from Martin Liška <marxin at gcc dot gnu.org> ---
Nice, confirmed. There's minimal reproducer:

cat float-cast-overflow-1.i


int
main (void)
{
  volatile double d;

  volatile long long ll;
  d = 0.0;
  d = 0x7fffffffffffffffLL;
  (ll) = (d) -5.0;

  return 0;
}

I'll take a look. Thanks.
