Here is a C code which makes this a regression, also I moved this to the target component instead of 
rtl-optimization because x86 is the only one which uses reg-stack.  Also only -O3 is needed to 
reproduce the ICE.
double wavetoyfo_deriv (double *fm2, double *fm1, double *f0, double *fp1,double *fp2, double 
*dx,int *dir)
{
 double __result_wavetoyfo_deriv;
 int T0 = *dir;
 if (T0)  goto nT0;
 __result_wavetoyfo_deriv = (*fp1 - *fm1) / *dx * 2.0;
 goto end;
nT0:
 if (T0 != -1) {cctk_warn(); goto end;}
 __result_wavetoyfo_deriv = (*fp1 - *fm1) / *dx * 2.0;
 goto end;
end:
  return __result_wavetoyfo_deriv;

}
