I think the line of thought is that the number -2147483648 == -huge(0)-1 is not a valid integer number as it is outside of Fortran's numerical model, which assumes that the smallest and the largest number only differ by the sign. See "13.4 Numeric models", paragraph 2 of the Fortran 2008 standard [1]. (While the most common binary integer representation in hardware allows for integers ranging from -huge(0)-1 to huge(0).) With the same argument, gfortran also rejects such integer literals in the source code. However, there the flag -fno-range-check can be used to still accept the value. For I/O, I concur that being able to write such a number but not being able to read it back it, is unexpected and should be fixed.
