--- Comment #1 from kargl at gcc dot gnu.org ---
Using -fdump-tree-original (and removing the IO code), 
one gets

anintbug ()
{
  real(kind=16) q1;
  real(kind=16) q2;
  real(kind=16) q3;

  q1 = 2.33181505644407999969482421875e+14;
  q2 = roundq (q1);
  q3 = 2.33181505644408e+14;

}

So, gfortran is calling the libquadmath routine roundq.
I've changed the component from fortran to libquadmath.
This also appears to fail with all versions of gfortran.
