Long story short. Open C has fixed their part for their next release (1.7), but
there is issue with RVCT compiler that will still make this not to work.

"The problem comes from the fact that the following code is not equal in
results:
double dnan = std::numeric_limits<double>::quiet_NaN();
int K = 13;
1.  if(!(dnan <= K))
is evaluated to false case;
bool temp = (dnan <= K);
if(!temp)
is evaluated to true case."

Above is happening if -02 optimatisation is used. with -O0 both cases evaluate
the same way.

So unfortunately we need to do a workaround until RVCT is getting fixed.
