Yes, I'm seeing the same thing. Is this due to an old version of gcc or
something? I'm using "gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516".

Yes, it's not present with a newer gcc, so this is a known issue (and it
sounds like it won't be fixed (from when I reported a similar thing)),
so I'm closing this bug report.
