(In reply to comment #2)
> It seems that, above a given size, gfortran declares the array as non-static:
Does not matter, the front-end is supposed to error out when the array's size
has overflowed.
The DECL_SIZE_UNIT is <integer_cst 0x42e64800 overflow -34359738368>
See the overflow. There were a couple of bugs about the C, C++ and Ada
front-ends that were like this bug (I cannot find them currently).

The test case in comment#1 now compiles without error and segfaults when run.

------- Comment #5 from jvdelisle at gcc dot gnu dot org 2006-09-20 03:48 -------
I think this is fixed. If I increase the size of the parameter I get the
expected error message.
program kk
implicit none
integer, parameter :: N=65535, M=N/2-1
real, dimension(N,N) :: input
call random_number(input)
end program kk
[jerry@quasar pr19654]$ gfc pr19654.f90
pr19654.f90: In function ‘MAIN__’:
pr19654.f90:4: error: size of variable ‘input’ is too large
I think this is fixed.

It seems that, above a given size, gfortran declares the array as non-static:
$ cat a.f90
program kk
implicit none
integer, parameter :: N=32768**2
real, dimension(N) :: input
call random_number(input)
end program kk
$ diff a.f90 b.f90
3c3
< integer, parameter :: N=32768**2
---
> integer, parameter :: N=32765**2
$ diff a.f90.t02.original b.f90.t02.original
3c3
< real4 input[1073741824];
---
> static real4 input[1073545225];
10c10
< parm.0.dim[0].ubound = 1073741824;
---
> parm.0.dim[0].ubound = 1073545225;
$ gfortran -fdump-tree-original a.f90
a.f90: In function ‘MAIN__’:
a.f90:5: internal compiler error: in tree_low_cst, at tree.c:3816
$ gfortran -fdump-tree-original b.f90
b.f90: In function ‘MAIN__’:
b.f90:4: error: size of variable ‘input’ is too large
Maybe this information will be useful to our gfortran gurus.

Confirmed, reduced (and self contained) testcase:
program kk
implicit none
integer, parameter :: N=32768, M=N/2-1
real, dimension(N,N) :: input
call random_number(input)
end program kk
