In Fortran 90/95 an assumed shaped array is passed with information
about dimensionality, sizes and strides. Some compilers do this by
passing an array descriptor instead of the actual array (like the
intel compiler), others may do different. I specifically ask for
the gfortran behavior - though it is maybe appropriate to file
a bugreport for the missing documentation about this.
