--- Comment #3 from Bill Lipa <dojo at masterleep dot com> ---
Thanks for looking at it. I studied it further and it seems that -O2 is the
culprit. Could you please try to reproduce with -O2?
$ gfortran -O2 res.f
$ ./a.out
At line 8 of file res.f (unit = 1, file = 'resultav4.dat')
Fortran runtime error: Read past ENDFILE record
