[Bug fortran/31594] New: gfortran failed to compiled a 'valid' code

[deji_aking at yahoo dot ca]

The attached fortran code (a smaller section cut and paste from original) was
generated by a custom preprocessor. The code very much seems to be valid
fortran 77, though its has some weird tab spacings; It compiles (and executes)
fine with pgf90 and ifort-8.x. The compile time error is as below (same with 
gfortran-4.1.2, 4.2 and 4.3.0 trunck build);

[armnlib@agape ~]$ gfortran -c -fcray-pointer adw_test.f 
adw_test.f:61.9:

         a(m,1) = p(m,1) * F_in  (o1(m,1)-1) + p(m,2) * F_in  (o1(m,1)) 
        1
Error: Unclassifiable statement at (1)
adw_test.f:90.8:

     %(m,3) * F_in  (o1(m,3)+1) + p(m,4) * F_in  (o1(m,3)+2)            
       1
Error: Expected PARAMETER symbol in complex constant at (1)
adw_test.f:94.8:

     %(m,3) * F_in  (o3(m,3)+1) + p(m,4) * F_in  (o3(m,3)+2)

Your lines are too wide, hoping that bugzilla will not mess up the formatting
I'll quote an example:
         1         2         3         4         5         6         7
123456789012345678901234567890123456789012345678901234567890123456789012345
          a(m,1) = p(m,1) * F_in  (o1(m,1)-1) + p(m,2) * F_in  (o1(m,1)) + 
     %p(m,3) * F_in  (o1(m,1)+1) + p(m,4) * F_in  (o1(m,1)+2)
                                                                        ^^
Per the standard, fixed form lines are 72 characters and everything beyond is
ignored, so the plus is not read.  The -ffixed-line-length option should solve
your problem.

Closing as INVALID.

To the reporter:
Even though this is already (correctly) closed as INVALID, please let us know
if your code does compile and run correctly if you compile with the suggested
extra command line option, -ffixed-line-length.

Yes, sorry, I forgot to say that.

Yes adding compiling with -ffixed-line-length-80 solved the issue for me,
thanks to you both. I've noticed the original author of that code used tabs in
a couple of space he should have used spaces, the other compilers I tried with
probably sees the tab as a single separator while gfortran fleshed it out to 3
spaces. I've added -ffixed-line-length-80 to the Makefile to handle similar
other cases in the model.
