This smells of a lack of default constructors for each of the types. This might be at the issue when attempting to cast and receiving the noted error.

The first line is not trying to invoke the assignment operator. It is trying to convert m_baseType to type DerivedType, then copy that using the copy constructor.

There is no copy constructor call in the first line. If anything, the default constructor of the DerivedType would be invoked, followed by an attempt to invoke an assignment operator, if one existed with the BaseType as the argument.
