--- Comment #5 from vehre at gcc dot gnu.org ---
Completely right, the initial test is still not compilable. But this is because
assigning to an allocatable component in an initializer is not allowed by the
standards:
F2003, 7.1.7 (3) and also in
F2008, 7.1.12 (3).
So the correct code would be:
module A
Type T
character(LEN=:), allocatable :: S
end type
Type(T) :: TestObj = T(NULL())
TestObj%S = 'string'
contains
end module
which compiles and runs w/o error.
Standard compliant implementation is tested for in
gfortran.dg/alloc_comp_init_expr.f03
only far allocatable arrays, but that's near enough for char arrays for me.
