Ok, that makes more sense. That was changed in commit f1e9f6bbfa53, and in the
discussion for that patch it was deemed that no callers actually suffered from
the leak as they were exiting (or erroring out) on error, so it was never back-
patched.

That still holds true today, so I don't see a big incentive to spend energy on
backpatching that since it mainly serves to silence analyzers. Grepping for
the pattern of allocating in the declaration doesn't reveal any other codepaths
where the allocation leaks like this.
