I just had a look at http://gcc.gnu.org/wiki/Fortran2003Status, where
one can find a big "YES" (in bold letters) under "recursive
input/output". So I guess
1) it is valid (at least in Fortran 2003),
2) gfortran should support it,
3) your frozen executable should probably be considered a bug.
Right?
