--- Comment #11 from Tobias Burnus <burnus at gcc dot gnu.org> --- (In reply to Dominique d'Humieres from comment #8) > Confirmed, however compiling the second test in comment #0, namely > > integer, allocatable :: i(:) > print *, NULL(i) > end > gives an ICE with 4.8.1 and trunk (4.9) "If an input item is a pointer, it shall be associated with a definable target and data are transferred from the file to the associated target. If an output item is a pointer, it shall be associated with a target and data are transferred from the target to the file." (F2008, "9.6.3 Data transfer input/output list") And NULL(...) isn't. Fixed by Paul's patch at http://gcc.gnu.org/ml/fortran/2013-11/msg00203.html
