program crash

Hi, thanks for sharing this awesome repo. I am wondering which version of ceres you are using since I got the following error: (I am using Ubuntu 16.04 + ROS Kinetic + Ceres 1.12.0 + Eigen 3.2.92. @gaowenliang @PeiliangLi )

my environment set: Eigen 3.3.4 + Ceres 1.13.0 + Ubuntu 16.04 + ROS Kinetic, a little bit different with yours. Seems there are something wrong with the Hessian Matrix in your solver. would you mind providing your rosbag data to me?

@gaowenliang I have tested the repo on my computer with the data (16448) you provided. But I still got this error.

I will try to update Ceres to 1.13.0, and let you know the results.

@gaowenliang After updating Ceres to 1.13.0, everything is OK. Thanks.
