Dammit, I had to try! :)
I've had to put a variety of "anti-hacker" features into the public instance, even though it runs on a (somewhat) throwaway EC2 instance.
Check out the source, and the LDPRELOAD stuff I do to try and make the compilers vaguely secure...!
template<class T> struct Loop { Loop<T*> operator->(); };
Loop<int> i, j = i->hooray;
struct a{typedef int foo;};struct a1:a{};struct a2:a{};
#define X(b,a) struct a##1:b##1,b##2{};struct a##2:b##1,b##2{};
X(a,b)X(b,c)X(c,d)X(d,e)X(e,f)X(f,g)X(g,h)X(h,i)X(i,j)X(j,k)X(k,l)
X(l,m)X(m,n) n1::foo main(){}
Thanks for sharing those utterly evil examples though! :D
