Bug ID: 64613
Summary: <incomplete type> allocatable array after 4.7
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: ql.le at hotmail dot com
A small code to test:
```
integer :: x(2,3)
integer, allocatable :: y(:,:)
allocate(y(2,3))
x = reshape([1,2,3,4,5,6], [2,3], order=[2,1])
y = reshape([1,2,3,4,5,6], [2,3], order=[2,1])
print *, 'x', transpose(x)
print *, 'y', transpose(y)
end
```
On 4.7, gdb works fine with both x and y
```
[qlle@(none) ~]$ gdb --version | head -n1
GNU gdb (GDB) Fedora (7.4.50.20120120-54.fc17)
[qlle@(none) ~]$ gfortran --version | head -n1
GNU Fortran (GCC) 4.7.2 20120921 (Red Hat 4.7.2-2)
(gdb) i lo
x = (( 1, 4) ( 2, 5) ( 3, 6) )
y = (( 1, 4) ( 2, 5) ( 3, 6) )
(gdb) p y(:,2)
$1 = (2, 5)
(gdb) p y(2,:)
$2 = (4, 5, 6)
(gdb) show language
The current source language is "auto; currently fortran".
```
However on 4.9, `<incomplete type>` was shown instead:
```

y = <incomplete type>
```
