[Boost-users] [Proto] POD expression can't be used in std::vector

I have a expression who use BOOST_PROTO_EXTEND to be used as a POD type
and I have a class inheriting from this expression to build a terminal 
class.

When I build a std::vector of this terminal class using vector(size_t n) 
constructor I got the following error :

/usr/include/c++/4.3.2/bits/stl_uninitialized.h:192: erreur: no matching 
function for call to ‘_Construct(const 
nt2::cmplx_expr<boost::proto::exprns_::expr<boost::proto::tag::address_of, 
boost::proto::argsns_::list1<nt2::cmplx_expr<boost::proto::exprns_::expr<boost::proto::tag::terminal, 
boost::proto::argsns_::term<std::pair<float, float> >, 0l> >&>, 1l> >, 
const nt2::cmplx<float>&)’

And same for _Destruct()

Seems & is used on the expression instead of the terminal class (a bit 
like the cout bug we found earlier).

Is it a proto bug or a std bug ?
