I think problems come from arrays, fortran derived types and pointers.

With arrays the problem come with assumed-shape array, array pointer and
allocatable array.
With fortran derived type the problem come from array component of the
above type.
Each fortran compiler has his own representation of pointer.

One way to avoid the problem is to code wrapper to translate from
fortran 90 to fortran 77
when arrays and pointers are involved.
