--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  Same with -g -fdebug-types-section -flto -ffat-lto-objects

Note -fdebug-types-section has known issues with LTO, it shouldn't be used.

In fact I asked whether we can remove it ...

I think I've seen this particular bug before as well.=
