Multiplying one-dimensional arrays with matrices using Eigen

Question

I was wondering why this doesn't work with Eigen:

MatrixXd A = MatrixXd::Random(3, 10);
Array<double, 1, Dynamic> x = Array<double, 1, Dynamic>::Random(10);
MatrixXd y = x.matrix() * A.transpose();

while this works:

MatrixXd A = MatrixXd::Random(3, 10);
Array<double, 1, Dynamic> x = Array<double, 1, Dynamic>::Random(10);
MatrixXd y = MatrixXd(x) * A.transpose();

and this also works:

MatrixXd A = MatrixXd::Random(3, 10);
ArrayXXd x = Array<double, 1, Dynamic>::Random(10);
MatrixXd y = x.matrix() * A.transpose();

My compiler gives me the following error message for the first example (clang-500.2.79):

code/Eigen/src/Core/ArrayWrapper.h:178:56: error: cannot initialize return object of type 'ScalarWithConstIfNotLvalue *' (aka 'double *') with an rvalue of type 'const Scalar *' (aka 'const double *') inline ScalarWithConstIfNotLvalue* data() { return m_expression.data(); }
