            Bug ID: 34276
           Summary: GDB shows wrong value of array elements.
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: fortran
          Assignee: unassigned at sourceware dot org

  Target Milestone: ---

$ cat test.f90 
program test
  implicit none

  type :: arr
    integer, allocatable :: f (:)
  end type

  type(arr), dimension(2) :: keys
  allocate (keys(1)%f(2))
  allocate (keys(2)%f(3))
  keys(1)%f(1) = 1
  keys(1)%f(2) = 2
  keys(2)%f(1) = 3
  keys(2)%f(2) = 4
  keys(2)%f(3) = 5
  print *, keys(1)%f(1)
  print *, keys(2)%f(1)

$ gfortran -g -o test test.f90
$ gdb -q test
Reading symbols from test...
(gdb) b 16
Breakpoint 1 at 0x146f: file test.f90, line 16.
(gdb) r
...

Breakpoint 1, test () at test.f90:16
16        print *, keys(1)%f(1)
(gdb) p keys(1)
$1 = ( f = (1, 2) )
(gdb) p keys(2)
$2 = ( f = (3, 4, 5) )
(gdb) p keys
$3 = (( f = (1, 2) ), ( f = (1, 2) ))

Notice the difference when keys(2) and keys are printed. In case of keys, the
2nd dimension is wrong. GDB is duplicating values from the first dimension.
