Closing since Box::leak is stable in nightly and will make its way to stable in 1.26.0.

I was confused why this was allowed to stabilize, but it appears that the bug that made this API unsound was fixed?

@gankro https://play.rust-lang.org/?gist=66d0329787975630e4f0cc62da61ed46&version=stable&mode=debug

The dupe mechanism doesn't work anymore at least.

Should we escalate this to a new issue with P-high?

Nope, just leaving a historical note for anyone else who was confused. Although if anyone knows when this was fixed (and if a test was added?) that would be good to note.
