I have

$ gcc-8 --version
gcc-8 (SUSE Linux) 8.2.1 20180831 [gcc-8-branch revision 264010]

but I can't trigger anything with it either.

So I had a report about a randconfig from the 0day robot guys which
doesn't look like allmodconfig but which triggered some of the issues
you're seeing and I have fixes for that one which we wanna queue after
-rc1.

You could try them to see if they fix your warnings too. First take the
2 here:

and then this one ontop:

Thx.
