--- Comment #2 from aruopp at gmx dot de ---
Hi,

compilation of code works without any problems.
Only if I execute the code, the problem exists with this error message.
The file 'polarfile_1.dat' is written during executing xfoil, but no values are
written into the file.

I tried to fix it, since error message during run points to mentioned code line
in iopol.f, at line 652 (see previous error message with link):

DO IA = IA1, IA2
     OPEN(LU,FILE=FNPOL,STATUS='OLD',POSITION='APPEND',ERR=90)

       WRITE(LU,LINEF)
     &         (CPOL(IA,IPOL(KP)), KP=1, NIPOL),
    &        ((CPOLSD(IA,IS,JPOL(KP)), IS=1, 2*NBL), KP=1, NJPOL)
     CLOSE(LU)
     ENDDO

But this didn't work, too.

Why is it working with an older gcc-version?

I will try to make a small code example but I'm not a fortran expert.
