No change in GCC 11. FWIW, I tried the patch for pr98465 but it doesn't help:

We should make sure the suppression works the same way with and without -flto.

I can give it another try in the next stage1. It's not easy though.

Note that this appears to be affecting the gcc source tree.
Attempting a build with --with-build-config=bootstrap-lto --enable-werror
errors out with:

Yes but lto bootstrap disables werror on purpose so you adding --enable-werror
is not supported.

--- Comment #10 from pefoley2 at pefoley dot com ---
It does? I wasn't aware of that.
My read of the configure options is that the two options are tangential.
And from a quick skim, I couldn't find anything that made enabling lto suppress
Werror.
Besides, regardless of whether it's supported or not, it's another example of
this issue in the wild.
