Here is a log that can be used as a testcase
1> cat main.F
program test
integer myarr(10)
data myarr /1,2,3,4,5,6,7,8,9,0/
print *, myarr(1)
end
>How-To-Repeat:
$/gcc/v4.1.2/bin/gfortran -g main.F
$/gdb/v6.6/bin/gdb ./a.out
(gdb) b main.F:4
Breakpoint 1 at 0x8048569: file main.F, line 4.
(gdb) run
Starting program: /home/satyag/test/gf/a.out
Breakpoint 1, MAIN__ () at main.F:4
4 print *, myarr(1)
Current language: auto; currently fortran
(gdb) p myarr(1)
$1 = 2
(gdb) quit
The program is running. Exit anyway? (y or n) y
$gcc/v3.2.3/bin/g77 -g main.F
$gdb/v6.6/bin/gdb ./a.out
(gdb) b main.F:4
Breakpoint 1 at 0x8048806: file main.F, line 4.
(gdb) run
Starting program: /home/satyag/test/gf/a.out
Breakpoint 1, MAIN__ () at main.F:4
4 print *, myarr(1)
Current language: auto; currently fortran
(gdb) p myarr(1)
$1 = 1
(gdb) quit
The program is running. Exit anyway? (y or n) y
