A modification of your code to print decimal shows
x = 2806196910506780709
x*x = -5105260488395614887
y = 9223372036854775807
The bit model specifically states that "The interpretation of a
negative integer as a sequence of bits is processor dependent."
The definition of the IAND intrinsic also states "The model for the
interpretation of an integer value as a sequence of bits is in
13.3". Unfortunately, Fortran does not have an unsigned integer
type.
