This code shouldn't work:
------------------------------
import std.stdio;
struct ID
{
    immutable int value;
}

struct Data
{
    ID id;
}
void main()
{
    Data data = Data(ID(1));
    immutable int* val = &data.id.value;
    writeln(*val); // 1
    data = Data(ID(2)); // <- This line shouldn't be allowed.
    writeln(*val); // 2
}

There are several bugs that match the summary line you had.  See issue 2573.

This is closely related to issue 2625.  The solution is given in issue 2625 comment 4.
