I take that back. The example is correct. This code...
-----
import std.math;

void main()
{
     real x;
     FloatingPointControl fpctrl;
     fpctrl.enableExceptions(FloatingPointControl.severeExceptions);
     double y = x*3.0;
}
----
results in:
object.Error: Invalid Floating Point Operation

However, it seems that the compiler is no longer creating variables of 
type double and float as signalling NaNs. That's a bug.
