The patch fixes the issues of comment 0.
However, one should go through the lengthy, convoluted thread at
http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/f014195ccf7b93e6/
to check whether it contains some still-unfixed issues.

The thread is too convoluted for me. Is this still an issue?

"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
