Indeed.  But, hmm, that's unfortunate, as my commit
r12-3498-g6c79057fae6bbb36c4a4fd61c5b7107a16b71b17 "Don't maintain a warning
spec for 'UNKNOWN_LOCATION'/'BUILTINS_LOCATION' [PR101574]" has been meant =
to
generally resolve this issue (per my analysis/understanding) -- well, maybe=
 it
did, and there really is another issue here?

Are you guys able to reliably reproduce the problem?  Asking because for me=
, it
was very flaky: some (seemingly random) change elsewhere in the compiler, a=
nd
PR101574 often didn't reproduce anymore (but came back later).  (But really
have not anymore seen it since the aforementioned commit.)

PR101204 and PR101292 may or may not be relevant, too.=
