I have no experience with placement new and delete so maybe someone can double check my assumptions.

CMSFPage uses a custom placement new operator declared in class scope. This does little else than perform an assert and call malloc.  Because placement new was used, as long as an exception is not called in new, delete will not be automatically called. This appears to be the expected behavior as the class maintains a reference count and calls delete on itself when it releases the last reference.  This calls the destructor and frees up the memory (probably undefined behavior to use delete to free malloced memory but I'm not the maintainer).  Not sure what the pre-c++11 behavior was but if there is an exception thrown during new, there needs to be a delete to call.  Marking the placement new operator "noexcept" doesn't seem to suffice. To satisfy this requirement, the patch defines a delete member operator that does nothing but call "free" on its pointer and zero it. AFAIK, it should never have to be called.
