cv::Mat_ to std::vector conversion

I use OpenCV 2.0, there is a method in the cv::Mat_<_Tp> class:

// conversion to vector.
operator vector<_Tp>() const;

When instantiated, the implementation does not compile on MSVS 2005:

template<typename _Tp> inline Mat_<_Tp>::operator vector<_Tp>() const
{
    CV_Assert( rows == 1 || cols == 1 );
    return isContinuous() ? vector<_Tp>((size_t)(rows + cols - 1), (_Tp*)data) :
        (vector<_Tp>)((Mat_<_Tp>)this->t());
}

Is it a new fancy constructor of std::vector that takes size_t and _Tp* from TR1 or something?

I thought they could just initialize the vector by an iterator instead:

vector<_Tp>((_Tp*)data, (_Tp*)data + rows + cols - 1)

Is it a bug, or don't I know something?

UPD. Compiler error text:

No, there are new constructors from rvalues in C++0x, but nothing like the one used here.

If isContinuous() means that all vales are the same, you could possibly use vector<_Tp>((size_t)(rows + cols - 1), *(_Tp*)data) to make copies of the first value.

Your iterator version seems correct otherwise.
