--- Comment #12 from Mikael Morin <mikael at gcc dot gnu.org> --- (In reply to anlauf from comment #8) > Enabling derived types does not work when they occur in an array constructor, > and the code would ICE on empty constructors of derived type. > Looking at the code, I couldn't foresee where the ICE would happen, so I tried it myself. I see no ICE here. diff --git a/gcc/fortran/trans-array.cc b/gcc/fortran/trans-array.cc index 04b5e30b96a..4fd3fb65a54 100644 --- a/gcc/fortran/trans-array.cc +++ b/gcc/fortran/trans-array.cc @@ -2941,10 +2941,6 @@ trans_array_constructor (gfc_ss * ss, locus * where) from constructor only for meaningful shape. */ bool zero_sized = zero_sized_array_p (expr); - /* FIXME: constant array constructors for DT have some issues... */ - if (expr->ts.type == BT_DERIVED || expr->ts.type == BT_CLASS) - zero_sized = false; - if (!zero_sized) nelem = gfc_constant_array_constructor_p (c); program test implicit none type :: t integer :: c end type t integer :: m(0) integer, allocatable :: n(:) call i call i(m) call i(n) allocate (n(0)) call i(n) call i([integer::]) ! expect "optional argument present: T" call i([1]) call j([t::]) contains subroutine i(str) integer, dimension(:), optional, intent(in) :: str write(6,*) 'optional argument present:', present(str) end subroutine i subroutine j(str) type(t), dimension(:), optional, intent(in) :: str write(6,*) 'optional argument present:', present(str) end subroutine j end program
