--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Gah, that's a compiler bug.
Martin, the -Wmismatched-tags warning adds loads of notes which are printed
unconditionally when -Wmismatched-tags is used. They need to be gated on
whether the actual warning is printed, so that you don't get orphaned notes for
warnings that are suppressed due to occurring in system headers.
I've changed the libstdc++ headers on trunk, but not on gcc-10, so you can
still reproduce it easily on that branch.
