see the example below along with gdb error.
$ cat g.f90
program test
integer,dimension(:),allocatable :: array
allocate (array(10))
array(10000000)=8
end
$ gfc g.f90
$ gdb a.out

------- Comment #4 from pinskia at gcc dot gnu dot org 2005-10-27 23:27 -------
This is more of a gdb bug as if I do:
set lang c
it prints out the array as a descriptor:
$2 = {data = 0x9a7f2d8, offset = -1, dtype = 265, dim = {{stride = 1, lbound =
1, ubound = 10}}}

"set lang c" didn't give me that output. What is your configuration, gdb ,
gfortran version and so on?
My gdb session is like this:
(gdb) whatis array
type = Invalid type code (3) in symbol table.
(gdb) set language c
Warning: the current language does not match this frame.
(gdb) whatis array
type = struct array1_int4
(gdb)

Oh, I did a "p array" since whatis is the same as ptype.

I believe this has been fixed by the patch (PR 22244):
http://gcc.gnu.org/ml/gcc-cvs/2007-12/msg00175.html
Note for gdb you still need the patches from:
http://sourceware.org/ml/gdb-patches/2007-11/msg00438.html
