Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Changed between 20161127 and 20161204.

$ cat z1.f90
program p
type t
integer, allocatable :: a(:)
end type
type t2
type(t), allocatable :: b(:)
end type
type(t) :: x
type(t2) :: y(2)[*]
allocate (x%a(2))
x%a = 123
y = t2([x])
end
