No offense intended, but a 1085 line source file is fairly
useless to us.  In particular, NAG's F95 compiler can't 
compile this code.  In addition, a single print statement
without additional context (such as the declaration of cor)
is also useless.  Can you cut this down to a self contained
example?

[Bug fortran/21432] gfortran does not support printing of namelists

[joe at confucius dot gnacademy dot org]

------- Additional Comments From joe at confucius dot gnacademy dot org  2005-05-07 03:43 -------
Sorry for the spew.  The code is generated by a preprocessor and I didn't
realize how large it would end up.  

The bug is that gfortran apparently does not support printing of namelists.  I
don't know if this is in the fortran standard or not, but it is a very common
compiler extension, and it is one that is hugely difficult to work around.

I've loaded up a new file that compiles with ifort.

[Bug fortran/21432] gfortran does not support printing of namelists

[kargl at gcc dot gnu dot org]

------- Additional Comments From kargl at gcc dot gnu dot org  2005-05-07 04:02 -------
Thanks for cutting it down!  The code is nonstandard according to
both the NAG compiler and Lahey's web base source code checker.
Lahey will compile the code if one does not ask for strict conformance 
to the standard.  Additionally, g77 compiles the code, so technically
it is a regression.

I've changed this bug to an enhancement request.  Perhaps, Paul Thomas
who just recently implemented the namelist features can fix this soon,
but we do have numerous conformance bugs on our plate.

No problem.  First things first :-) :-) :-)

In case you are wondering the bug reports I've been submitting come from trying
to compile a 20000 line iron core collapse supernova simulation.  It's the type
of nasty science code that you see a lot in the field, but it has been ported to
enough different platforms so that the bugs it picks up aren't too obscure.

Sorry if I appear dense, but where is the problem in changing

      namelist /cor/ a
      print cor
to
      namelist /cor/ a
      write (*,cor)

?

Or even.... horrible, horrible, horrible

       real  x, y, z
       namelist /a/ x, y, z
       x = 1
       y = 2
       z = 3
       print (*,a)
       end

works.
