--- Comment #3 from kargls at comcast dot net ---
Both Harald and Andrew have raised the undefined nature of your code.
The actual restriction is
F2023, 10.1.5.2.4, 174
The execution of any numeric operation whose result is not defined by
the arithmetic used by the processor is prohibited.
Note, this is not a numbered constraint so a Fortran processor can
do anything it wants with the code.
