if you look closer you'll see that particular warning will be
triggered at almost any point.
That is using method A will be fine with GCC/Clang version X but Y
will warn and vise-versa. Hence, developers tend to be opinionated
(annoyed really) on the topic.
The only two robust solutions that I know of are
- designated initalizers
- memset
Hence why I suggested the former.

IIRC some versions of GCC were doing funny things. Don't recall the
details, thus the "may".
If you're really bored and want to know the details, checking across
versions of GCC and its authors may be a good idea.
