Thank you for the patch - applied.

I don't see any MSVC errors with VS10. Do you have some code to reproduce this?

The following code fails to compile under VS9 (I don't have VS10 yet).  Switching to std::vector works just fine:

#include <Eigen/Core>

#include <Eigen/StdDeque>

int main()

{

    typedef Eigen::Matrix<float, 4, 4> Matrix4;

    std::deque< Matrix4, Eigen::aligned_allocator<Matrix4> > matrixDeque;

    return 0;

}

The compiler output is:
