In this case X comes from Ada.Numerics.Complex_Types.Abs(Y)
and Y came from Z**2, so it might well overflow. Float'Machine_Overflows
is False, so I can't expect an exception, but is an overflowed value
on Gnat/Windows something that is always False in a compare, and
generates garbage for float'image?
