This is an auto-filled bug because dev-libs/libtpms fails to compile. The issue was originally discovered on amd64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info.

Sorry, forgot: All warnings appeared after upgrading to gcc 10.1.0.
I've submitted a PR yesterday with 3 of 4 patches, and one i spun on my own; upstream has now patched it so I've re-pushed with upstream's version.
