--- Comment #4 from Jeffrey Walton <noloader at gmail dot com> --- This is kind of weird... When we tested with C++03 by adding -std=c++03, we got 4 more of them. The check-in of interest is https://github.com/weidai11/cryptopp/commit/7097546cfcf742cf. Is there really no way to troubleshoot or diagnose this? I'd really like to know what the section name is that's causing the problem.
