Following should compile.
----
struct X
{
    int n;
    const void opAssign(const X rhs) {}
}
struct S
{
    int n;
    const(X) x;
}
void main()
{
    S s;
    s = s;
}
----
test.d(14): Error: variable test.main.s cannot modify struct with immutable
members
----

S has implicitly defined opAssign, but it does not call field x's opAssign.
