Here is a reduced test case for this one:
program testmv2
type bar
integer, allocatable :: ia(:), ja(:)
end type bar
class(bar), allocatable :: sm,sm2
allocate(sm2)
select type(sm2)
type is (bar)
call move_alloc(sm2,sm)
end select
end program testmv2
In each TYPE IS/CLASS IS block we generate a temporary for the selector.
Apparently we need to set the correct attributes for the temporary.
