In this case, shared_ptr could not provide the "no throw" guarantee for
dereferencing the pointer. This is usually an important requirement for
My own discussion in c++-moderated with David Abrahams and others
convinced me, that in most cases like this you have to decide the following:
Which throw guarantees do we want/need?
- If "no throw" is importand, use assert
- otherwise use a well-documented exception
