--- Comment #1 from janus at gcc dot gnu.org ---
I can confirm that the code runs fine with 6.2 and 5.4, but segfaults with
trunk.
Slightly reduced test case:
program p
implicit none
type ac
end type
type, extends(ac) :: a
integer, allocatable :: b
end type
type n
class(ac), allocatable :: acr(:)
end type
type(n) :: s,t
allocate(a :: s%acr(1))
call nncp(s,t)
contains
subroutine nncp(self,tg)
type(n) :: self, tg
allocate(tg%acr(1),source=self%acr(1))
end
end
