--- Comment #9 from Martin Jambor <jamborm at gcc dot gnu.org> ---
The patch referenced in the previous comment was
https://gcc.gnu.org/pipermail/gcc-patches/2018-July/503072.html
but there were concerns about its effect in other circumstances. In
any event, I do not plan to work on this now so I am un-assigning
myself.

Even LLVM does this same thing.

What do you mean by "does this same thing?" Does it copy the structure
element-wise or does it copy it is a block like GCC does (and suffers the same
problem)?

It does a block copy like GCC.
