Hmm, since I see -Wmissing-braces mentioned, is there a chance that this
fixes/changes the c++20 behaviour reported in PR c++/126131?
Not sure, don't use designators in that case or disable the warning?
It is a case where omitting the designator on the anon union is invalid if
it is used in oother designators, even with the C++29 rules, and designating
the anon union member without {}s around it is what -Wmissing-braces is
supposed to warn about.
Changing the source is what I already prepared, but still this is a
strange inconsistency IMHO.
So, you think -Wmissing-braces is likely wrong in the C++20 or later
anonymous union case with designated initializers? I'll update PR 126131
accordingly. And I'll just test your patch and see what happens :-).
Thanks,
