As I said in comment #5, the limit was just pushed higher, but big writes on
preconnected units still fail:

$ gfortran a.f90 && ./a.out > bigfile
At line 3 of file a.f90
Fortran runtime error: End of record
$ cat a.f90
 real :: array(100000000)
 array(:) = 0
 write(*,*) array
end
$ ll bigfile

$ gfortran -v

You can look at the patch cited in comment #5 for where the problem lies. And
this is not really related to Janne's PR, I guess. It's specific to
preconnected units.
