<pre>```
struct foo {};
struct bar{
struct foo foo;
};
static const struct foo my_foo = {};
static const struct bar my_bar = {
.foo = my_foo,
};
```
Clang produces:
```
<source>:8:12: error: initializer element is not a compile-time constant
.foo = my_foo,
^~~~~~
```
GCC has no error.
A recent CI run on the Linux kernel failed for Clang on this patch:
