[Bug fortran/17031] New: Unclassifiable statement error with a pointer declaration

[deji_aking at yahoo dot ca]

Not sure this is bug, 'cos IMHO, this kind of declaration is rather archaic;
however it is compiled properly by pgf90 and intel compiler. Here is an example
of such statement;
>>
*
      real qswv,qswi,pcpr,qswinv,qswini,ta,coszs,qswd
      real alvsbar,alirbar,cdmbar,qsens,qevap
      real su,sv,st,sq
      pointer (pata, ta(ilg))
      pointer (pacoszs,coszs(ilg)), (paqswd,qswd(ilg))
      pointer (paqwv  , qswv(ilg)), (paqwi, qswi(ilg))
      pointer (papcpr ,  pcpr(ilg))
<<
compiling with gfortran gives;
>>
[deji@rhema deji]$ f95 -c -x f95 class271.f
 In file class271.f:1952
 
      pointer (pata, ta(ilg))
     1
Error: Unclassifiable statement at (1)
 In file class271.f:1953
 
      pointer (pacoszs,coszs(ilg)), (paqswd,qswd(ilg))
     1
Error: Unclassifiable statement at (1)
 In file class271.f:1954

I've attached a copy of the full code. I'm working on a model that have a bunch
of source codes with similar declaration statements in them.
Thanks.

This code make use of the Cray pointer, which is a nonstandard construct.
Cray pointers are #9 on the wishlist of extensions, but I doubt Cray pointers
will be implemented in the near future. http://gcc.gnu.org/fortran/extensions.html

That's sad and disappointing that tis will not be implemented (soon), which
means the model will forever continue to rely on the proprietary compiler.
Thanks very much for the explanation and the link.

According to a discussion on the fortran mailing
list, some initial work seems to have been done:

We now have a proposed patch for that. It should be commited as soon as
paperwork issues are resolved.
