[Bug fortran/18998] New: Gfortran produces wrong output (c/f to g77)

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

I'm sorry the summary seems so vague, I'm not so sure why it's behaving that way.
Executing the attached code (a simple i/o around a numerical recipe FFT
subroutine) produces the following;
[deji@rhema ~]$ gfortran fft2.for -o resu2
[deji@rhema ~]$ ./resu2
   0.000000       0.000000
   0.000000       0.000000
   4.000000       0.000000
   0.000000       0.000000
   0.000000       0.000000
   0.000000       0.000000
   0.000000       4.000000
   0.000000       0.000000
STOP 0
Doing the same using g77 produces;
[deji@rhema ~]$ g77 fft2.for -o resu2
[deji@rhema ~]$ ./resu2
  0.  0.
  0.  0.
  4.  0.
  0.  0.
  0.  0.
  0.  0.
  4.  0.

The g77 output is actually right and the gfortran one, wrong (swaping the
imaginary part for the real).
