<pre>When the first subobject of a structure within another structure is not a
signed integer (e.g. unsigned integer, char, short, long), it triggers a
-Wmissing-braces warning.
Reproducer:
struct s1 {
short f1; // "int f1" is fine.
};
struct s2 {
struct s1 f2;
int x;
};
struct s2 x = {0};
// warning: suggest braces around initialization of subobject
[-Wmissing-braces]
An earlier issue with the "universal zero initializer" was resolved with bug
21689 (Clang 6), but this one still remains.
Found in:
clang 7.0.0-1 (Arch Linux)
clang version 8.0.0 (trunk 348720) (llvm/trunk 348724)</pre>
