Comment:

 This change looks fine to me.  I looked into why it might be breaking with
 --enable-fragile-hardening (which our Travis builds also use) and it
 [https://travis-ci.org/isislovecruft/tor/jobs/341633581 appears to be an
 issue] with clang's LeakSanitizer detecting the leaks from #25127 ([https
 ://travis-ci.org/isislovecruft/tor/builds/341633577 the other GCC builds
 and non-Rust builds completed just fine]). After rebasing it on top of the
 #25127 fix, [https://travis-ci.org/isislovecruft/tor/builds/341658322
 clang seems happy].
