With the code here:
----
program pb
character*10 form
character*4093 str
str=' '
write(form,120) 3,0
write(str(1:3),form) 1.0d0 - 1.110223024625157D-16
print *,str(1:10)
120 format('(f',i2,'.',i2,')')
end
----
Compiled with gfortran 4.3.2:
the output is 2
With the gfortran 4.2.4
the result is 1 (which is the right one)
$ gfortran-4.3 -o pb pb.f && ./pb
2.
$ gfortran-4.2 -o pb pb.f && ./pb
1.

------- Comment #1 from domob at gcc dot gnu dot org 2008-10-17 15:42 -------
Confirmed on trunk, with this test:
program pb
write(*,'(F3.0)') 1.0d0 - 1.110223024625157D-16
end
Changing decimals display to a value larger than 0 outputs 1 correctly.

Fixed on trunk. I accidentally committed the patch with the wrong PR number in
the Changelog (37707)
This I will backport to 4.3 in a day.
