-// Regression test for Issue 25199: Check that one cannot hide a
-// destructor's access to borrowed data behind a boxed trait object.
-//
-// Prior to fixing Issue 25199, this example was able to be compiled
-// with rustc, and thus when you ran it, you would see the `Drop` impl
-// for `Test` accessing state that had already been dropping (which is
-// marked explicitly here with checking code within the `Drop` impl
-// for `VecHolder`, but in the general case could just do unsound
-// things like accessing memory that has been freed).
-//
-// Note that I would have liked to encode my go-to example of cyclic
-// structure that accesses its neighbors in drop (and thus is
-// fundamentally unsound) via this trick, but the closest I was able
-// to come was dropck_trait_cycle_checked.rs, which is not quite as
-// "good" as this regression test because the encoding of that example
-// was forced to attach a lifetime to the trait definition itself
-// (`trait Obj<'a>`) while *this* example is solely
