--- Comment #1 from Simen Kjaeraas <simen.kjaras at gmail.com> ---
This is mostly expected. When a nested struct has a method, that method has
access to the context of the function in which it is defined, so you can do
things like this:

void fun() {
    int i = 0;
    struct S {
        void gun() { ++i; }
    }
    S s;
    s.gun();
    assert(i == 1);
}

Since the nested struct may be passed to other functions or even returned from
the function that created it, this context pointer needs to be embedded in the
struct.

Regardless, in your case the context pointer is strictly unnecessary, and could
be elided. That makes this issue a duplicate of issue 10276.

The workaround for this issue is to mark the struct as static.
