--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
You compile without optimization?  (no -O2 for example?)

Note that I forgot that with -flto a single preprocessed file doesn't really
help to reproduce.  We'd need a minimal set of preprocessed sources where

g++ <flags> -flto -r -nostdlib <preprocessed sources>

reproduces the issue (so compile & link on the same command-line preferably).
With -r -nostdlib you avoid linker errors later.

Reducing is easier with -flto-partition=1to1 (if the issue reproduces with
that...).
