Re: [eigen] ceres-solver fails to build with eigen 3.3~beta2

[Christoph Hertzberg <chtz@xxxxxxxxxxxxxxxxxxxxxxxx>]

I can reproduce this with the following simplified test:

The second 1.0* is optional (but should be added as unit test).

I guess Gael will be able to fix this (I'd have to take a deeper look 
into some recent changes first).

N.B.: scalar * Mat::Ones(rows, cols) could be simplified to 
Mat::Constant(scalar, rows, cols).
