--- Comment #10 from Carl Ponder <CPonder@nVidia.Com> ---
Stopping at line 70 puts it right after the array-allocation but before the
array-writes are happening:

     62   implicit none
     63   integer, intent(in) :: N
     64   integer ( kind = 4 ) i
     65   integer ( kind = 4 ) :: x(1:N)
     66 
     67 !
     68 !  X = { 0, 1, 2, 3, 4, ?a, ?b, ?c, ?d, ?e }.
     69 !
     70   do i = 1, 5

The data-state still says initialized, even though the array contains junk
values:

(gdb) print x
$2 = (40, 0, 117993993, 0, 117993992, 0, 69349896, 0, 19, 0)
(gdb) print &x
$3 = (PTR TO -> ( integer (10))) 0xffeffed90
(gdb) monitor xb 0xffeffed90 40
                  00      00      00      00      00      00      00      00
0xFFEFFED90:    0x28    0x00    0x00    0x00    0x00    0x00    0x00    0x00
                  00      00      00      00      00      00      00      00
0xFFEFFED98:    0x09    0x72    0x08    0x07    0x00    0x00    0x00    0x00
                  00      00      00      00      00      00      00      00
0xFFEFFEDA0:    0x08    0x72    0x08    0x07    0x00    0x00    0x00    0x00
                  00      00      00      00      00      00      00      00
0xFFEFFEDA8:    0x08    0x32    0x22    0x04    0x00    0x00    0x00    0x00
                  00      00      00      00      00      00      00      00
0xFFEFFEDB0:    0x13    0x00    0x00    0x00    0x00    0x00    0x00    0x00

I'm checking with the compiler guys on this.
