 State-Changed-Why:
     Thank you for your bug report.
     
     This is not valid C++ code.  Types held in standard
     containers must be assignable and copyable.  Since objects
     of type B cannot be assigned, they cannot be contained in a
     vector.
     
     The compiler tries to point this out; look for the 2 lines
     with _STL_ERROR in the (trimmed) copy of the error messages
     you reported:
     
     
     classB.h: In static member function `static _Type
        _STL_ERROR::__assignment_operator_requirement_violation(
     _Type) [with _Type = B]':
     classB.h:22: `B& B::operator=(const B&)' is private
     /ncsu/meeberdt/local/gcc-curr/include/g++-v3/bits/concept_c
     hecks.h:370: within this context
     classB.h: In static member function `static _Type
        _STL_ERROR::__const_parameter_required_for_assignment_op
     erator(_Type, const _Type&) [with _Type = B]':
