[eigen] compilation failed with devel branch (works fine with 2.0.5)

[WANG Xuewen <xuewen.wang@xxxxxxxxx>]

Hi,

I have the following example that compiles fine using 2.0.5 but failed 
with devel branch.

#include <eigen2/Eigen/Core>
#include <eigen2/Eigen/Array>
#include <eigen2/Eigen/LU>

static const int NMaxTinyMatrixDimension = 7;

typedef Eigen::Matrix<double, Eigen::Dynamic, Eigen::Dynamic,
Eigen::RowMajor | Eigen::DontAlign,
NMaxTinyMatrixDimension, NMaxTinyMatrixDimension>
TinyRMatrix;

void TestInverseCompilation()
{
TinyRMatrix m;
m.setIdentity(5, 5);
TinyRMatrix inverse = m.inverse();
}


The error message is:

I don't think that the function inverse is deprecated so I wonder if 
this is a regression or I should modify my code(but I don't know how though)

thanks,
