I have a simple case where CLASS(*) leads to an ICE.
If it doesn't fit here, please feel free to move it elsewhere.
module gfcbug121
implicit none
type myobj
class(*), allocatable :: x
contains
procedure :: print
end type myobj
contains
subroutine print(this)
class(myobj) :: this
end subroutine print
end module gfcbug121
I get:
