Finnally found a C example:
Compile the folllowing with -O2 -ffast-math -ftrapping-math and you will get the failure.

#include <math.h>
int Fore (double lo, double hi)
{
  int r;
  double t;
  double t1;
  double t2;
  int tt;

  t1 = fabs(lo);
  t2 = fabs(hi);
  t = t1 >= t2 ? t1 : t2;
  tt = (t >= 1.0e+1);
  if (tt == 0) goto L12;

L11:;
  r = 2;
  goto L2;

L12:;
  r = 2;

L1:;
  t = t / 1.0e+1;
  r = r + 1;
  tt = (t >= 1.0e+1);
  if (tt == 0) goto L1;

L2:;
  return r;

}
