Visual Studio 2013 crash when I'm trying to compile Eigen

Question

The following simplified code:

#include "Eigen/Core"

template <int n>
Eigen::Matrix<float, 1, n> init_array(float a)
{
    Eigen::Matrix<float, 1, n> res;
    res.fill(a);
    return res;
}

int main()
{
    Eigen::Matrix<float, 1, 3> a = init_array<3>(1.0f);
}

leads to the Visual Studio crash:

main.cpp(13): fatal error C1001: An internal error has occurred in the compiler.
   (compiler file 'msc1.cpp', line 1325)
   To work around this problem, try simplifying or changing the program near the locations listed above.

I downloaded the latest version of Eigen 3.2.5. I have the Visual Studio Professional 2013 Version 12.0.21005.1.

Does anybody know a workaround?

I was having this same problem. Apparently, you should update your Visual Studio 2013. This worked for me. This problem was reported to Microsoft and they fix it in the update 2 (current is 5)
