Confirmed on trunk and 4.6.2. The failure is the same as in pr51864.
Revision 162456 is OK,
revision 164728 gives the ICE.

Reduced test case, which also illustrates another ICE:
module EcoSystem_ml
implicit none
type, public:: Deriv
character(len=10) :: name
end type
character(len=8), public, dimension(1), parameter :: &
DEF_ECOSYSTEMS = (/ "Grid " /)
type(Deriv), save :: DepEcoSystem != Deriv(DEF_ECOSYSTEMS(1))
! ^^^^ ICE in gfc_conv_string_init
contains
subroutine Init_EcoSystems()
DepEcoSystem = Deriv(DEF_ECOSYSTEMS(1))
! ^^^ ICE in gfc_conv_array_constructor_expr
end subroutine Init_EcoSystems
end module EcoSystem_ml

(In reply to comment #4)
> type(Deriv), save :: DepEcoSystem = Deriv(DEF_ECOSYSTEMS(1))
Here, the problem is that in
#0 gfc_conv_string_init (length=0x2aaaacf3b720, expr=0x16c1170)
expr->type == EXPR_ARRAY. Hence, the following fails:
gcc_assert (expr->expr_type == EXPR_CONSTANT);
#1 in gfc_conv_initializer at fortran/trans-expr.c:4940
#2 in gfc_conv_structure at fortran/trans-expr.c:5396
#3 in gfc_conv_initializer at fortran/trans-expr.c:4933
#4 in gfc_get_symbol_decl at fortran/trans-decl.c:1476
Also that version works with GCC 4.5.

Also 2010-08-28-r163612 fails.
I wonder whether the patch for PR 44857 (2010-08-04, Rev. 162863) is the
culprit:

FIXED on the trunk (for 4.7) and on the 4.6 branch.
Thanks for the report!
If the issue blocks you, you could consider downgrading to 4.5. Alternatively,
you could build GCC yourself or download a newer [than today] 4.6 or pre-4.7.0
build. (Cf. http://gcc.gnu.org/wiki/GFortranBinaries and
http://gcc.gnu.org/wiki/GFortranDistros )
