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

["deji_aking at yahoo dot ca" <gcc-bugzilla@gcc.gnu.org>]

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))
