Yes, I believed it's fixed in GCC 11. GCC 11.2.1 20210728 (Red Hat 
11.2.1-1) does not warn me about it.

I installed into the emacs-28 branch the attached, which fixes it in a 
different way to make it a bit clearer to the reader that we're 
pacifying an inadequate compiler rather than executing odd code for an 
unknown reason.

There are a handful of other bogus warnings with GCC 11.2.1, which I'll 
try to get around to pacifying (I hope before GCC 12 comes out :-).
