I'm not familiar with project's backporting policies.
FWIW, this bug break Linux scheduler compilation with g++,
which is a big deal for me! :^)

I can only reconfirm this bug still exists with 8.2.0 after rediscovering it

Currently, the rules do not allow reordering member initialisation:

This is getting lengthy:
Please allow C99 semantics for "simple enough" stuff (read: C structs):
* allow reordering
* allow duplicating (possibly with warning),
* allow holes in the middle of arrays (1-

My standardspeak is very bad.
I think std::is_trivial_v types should have relaxed initialisation ordering,
because all C structs and unions are std::is_trivial_v.
If I understand this stuff correctly, or

It is not fancy.
C99 initialisers is the only feature where Modern C beats Modern C++.
