Vector of booleans have a specific implementation in C++, that directly use
bits in order to optimize the space.
See http://www.cplusplus.com/reference/stl/vector/ for details (bottom of
the page).

I guess this specialization is not supported by RTT for now, and the
marshaling may be disturbed by the unmatching from bool to bit...
