! First the original problem: vocab_swap not being referenced caused
! an ICE because default initialization is used, which results in a
! call to gfc_conv_variable, which calls gfc_get_symbol_decl.
SUBROUTINE extend_lists1
type(VARYING_STRING),DIMENSION(list_size) :: vocab_swap
ENDSUBROUTINE extend_lists1
! Curing this then uncovered two more problems: If vocab_swap were
! actually referenced, an ICE occurred in the gimplifier because
! the declaration for this automatic array is presented as a
! pointer to the array, rather than the array. Curing this allows
! the code to compile but it bombed out at run time because the
! malloc/free occurred in the wrong order with respect to the
! nullify/deallocate of the allocatable components.
SUBROUTINE extend_lists2
type(VARYING_STRING),DIMENSION(list_size) :: vocab_swap
allocate (vocab_swap(1)%chars(10))
if (.not.allocated(vocab_swap(1)%chars)) STOP 1
if (allocated(vocab_swap(10)%chars)) STOP 2
