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. :-)
