Confirmed. It works with 4.7.





Here is a variant which fails with a different ICE:



 implicit none

 type :: c_stv

 end type

 class(c_stv), allocatable :: tmp

 call source(tmp)

contains

 subroutine source(y)

  type(c_stv), allocatable, intent(out) :: y

 end subroutine

end







internal compiler error: Segmentation fault

  call source(tmp)
