[Bug fortran/32027] New: [4.3 Regression] The "DO" variable isn't consistent after loop

[hjl at lucon dot org]

The change for bug 31399 makes the "DO" variable inconsistent after loop:

[hjl@gnu-2 loop-1]$ cat foo.f90 
  integer(kind=1) :: i
  integer(kind=8) :: c = 0

  do i = 1, 5, 1
    c = c + 1
  end do
  print *, i
  if (i /= 6) call abort
  do i = 1, 5, 2
    c = c + 1
  end do
  print *, i
  if (i /= 7) call abort
  end
[hjl@gnu-2 loop-1]$ /usr/gcc-4.3/bin/gfortran foo.f90 -static 
[hjl@gnu-2 loop-1]$ ./a.out 
    6
    5
Aborted
[hjl@gnu-2 loop-1]$ /usr/gcc-4.2/bin/gfortran foo.f90 -static 
[hjl@gnu-2 loop-1]$ ./a.out 
    6
    7
[hjl@gnu-2 loop-1]$
