Set Universe Polymorphism.
Section foo.
  Let U := Type.
  Let U' : Type.
  Proof.
    let U' := constr:(Type) in
    let U_le_U' := constr:(fun x : U => (x : U')) in
    exact U'.
  Defined.
  Inductive t : U' := .
End foo.

This bug is closed in trunk-polyproj, so I'll close it immediately; I'm reporting it so I have a number to give the bug in my test-suite.
