If this was assigning a pointer, that would make sense, but that isn't
what is happening. This is assigning the value of a non-const struct to
a const struct, which should be a copy operation, shouldn't it?

Oddly enough, this succeeds:

====
struct bar {
    int x,y;
};

int main() {
    struct bar a = { 2, 5 };
    const struct bar b = a.y ? *(struct bar*)(&a) : a;
    return b.y;
}
====

...so I don't actually know why this failed in the first place.

Anyway, it isn't important. :-)
