--- Comment #4 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
FWIW the analyzer branch can warn about comment #0, but only if the value gets
used, not simply that it escapes.

See e.g. the -Wanalyzer-use-of-pointer-in-stale-stack-frame warning within
https://godbolt.org/z/PAtqhB

Probably ought to warn about it simply escaping.
