I don't think my patch breaks this property.  After I write to
testval.float_testval, the subsequent bytes are still 0xff.  And if a
double is no smaller than a float, it works for the double test, too.

If we're trying to catch more-bits-than-appropriate comparisons,
shouldn't the *_resultval variables be in a union with a distinct
background pattern, too?  Say, zeros?
