Am I nuts?

I'm rather offended, having been bitten by this bug. Why is it even allowed to take a reference to a const reference, if it could be a copy?!?

#include <assert.h>

class Blah
{
public:
  const unsigned int &myfoo;
  Blah(const unsigned int &p):
    myfoo(p) {}
  const unsigned int getfoo()
  {
    return myfoo;
  }
};

int main()
{
  int foo(42);
  Blah baz(foo);

  ++foo;

  assert(foo == baz.getfoo());

  return 0;
}
