/* Hack alert.
* For reasons of simplicity and efficiency, we want to use raw pointers for iteration.
* However, shared_ptr::get() isn't defined when !m_sdata, although practically it gives NULL.
* Unfortunately, many of the MSVC (<= VS 2010) STL methods assert() that iterators are never NULL.
* Unfortunately, many of the MSVC (<= VS 2013) STL methods assert() that iterators are never NULL.
* So we fudge here by abusing 'this' so that our iterators are always !NULL.
