This is a fortran problem. It will never be given
a Severity of Critical or Major, which are typically
used by the GCC developers to denote bootstrap problems
or a problems with the C compiler.

Sorry. I was going by the documentation on the link ("crashes, loss of data,
severe memory leak"). Thanks for the information.

------- Comment #6 from kargl at gcc dot gnu dot org 2009-04-24 17:59 -------
The problem is due to the null() in
character(200), pointer :: descrip => null()
If you comment out this statement or remove '=> null()',
then the code compiles and runs. A slighly reduced testcase
is
module test_struct
interface assignment (=)
module procedure tao_lat_equal_tao_lat
end interface
type bunch_params_struct
integer n_live_particle
end type
type tao_lattice_struct
type (bunch_params_struct), allocatable :: bunch_params(:)
type (bunch_params_struct), allocatable :: bunch_params2(:)
end type
type tao_universe_struct
type (tao_lattice_struct), pointer :: model, design
character(200), pointer :: descrip => null()
end type
type tao_super_universe_struct
type (tao_universe_struct), allocatable :: u(:)
end type
type (tao_super_universe_struct), save, target :: s
contains
subroutine tao_lat_equal_tao_lat (lat1, lat2)
implicit none
type (tao_lattice_struct), intent(inout) :: lat1
type (tao_lattice_struct), intent(in) :: lat2
end subroutine
end module
program tao_program
use test_struct
implicit none
type (tao_universe_struct), pointer :: u
integer n
allocate (s%u(1))
u => s%u(1)
allocate (u%design, u%model)
n = 112
allocate (u%model%bunch_params(0:n), u%design%bunch_params(0:n))
u%model = u%design
u%model = u%design
end program

------- Comment #7 from pault at gcc dot gnu dot org 2009-04-25 18:06 -------
(In reply to comment #6)
With the pointer initialization, the assignment u%model = u%design
is translated to:
{
struct tao_lattice_struct D.1667;
D.1667 = *u->design;
tao_lat_equal_tao_lat (u->model, &D.1667);
if (D.1667.bunch_params.data != 0B)
{
__builtin_free (D.1667.bunch_params.data);
}
D.1667.bunch_params.data = 0B;
if (D.1667.bunch_params2.data != 0B)
{
__builtin_free (D.1667.bunch_params2.data);
}
D.1667.bunch_params2.data = 0B;
}
Thus the data pointers are doubly freed because they are not nullified in
u->design
Once the initialization is gone, the assignment becomes
tao_lat_equal_tao_lat (u->model, u->design);
and the cause of the problem has vanaished.

I have an "obvious" (ie. after three hours staring at it:-( ) fix that is
regtesting. I'd better take the PR!

By the way, David, thanks for the report!
