--- Comment #3 from federico <federico.perini at gmail dot com> ---
Right: here is a version where the object is initialized:=20

https://godbolt.org/z/o566cPG8P

I also see that for the versions that compile (e.g., 11.1.0), there's a wei=
rd
SEGFAULT error at this line:=20


    elemental logical function isa(this,i)
       class(t), intent(in) :: this
       integer, intent(in) :: i
       integer :: n
       n =3D merge(size(this%iloc),0,allocated(this%iloc))
       if (i>0 .and. i<=3Dn) then ! Segmentation fault here=20
          isa =3D this%iloc(i)>0
       else
          isa =3D .false.
       endif=20=20
    end function isa

So it at least compiles, but apparently the bug is hidden somewhere else?=
