Test case:

struct A
{
    ~this(){}
}

@safe struct B
{
    A a;
}

@safe void f()
{
    auto x = B.init;
}

dmd outputs:
Error: safe function '~this' cannot call system function '~this'

And no line number or type anywhere in message.
At very minimum it should state which type is used in first ~this and which in 
second.
