Description
This FN was introduced by the rustup #4628. To fix this major changes to the lint are probably necessary (https://github.com/rust-lang/rust-clippy/pull/4628#issuecomment-538574944).
A test for this FN already exists here:
https://github.com/rust-lang/rust-clippy/blob/e2393b09ac234aa19a2ffa368ef8d25ce645eaa3/tests/ui/escape_analysis.rs#L170-L174

Research direction
Start with the boxed_local lint and the referenced test in tests/ui/escape_analysis.rs at lines 170-174. Review the rustup-related change in PR #4628 and its discussion to understand the false negative; done means the existing test no longer exposes the incorrect lint behavior.
