[Ceres] double free or corruption (out), Aborted (core dumped)

[bigbigpark]

Hi

I am using CT-ICP, ICRA 2022 and found some errors in ct_icp.cpp. I successfully compile and built this package.
When I run this code, an error occured in the function of CT_ICP_CERES.
In my terminal it says,

double free or corruption (out)
Aborted (core dumped)

I debugged that code, I found where the problem starts.

ceres::Solve(ceres_options, problem.get(), &summary);

Here is my environment.
Ubuntu 20.04
cmake 3.18.0
gcc/g++ 9.4.0 Ceres solver 2.1.0
robin-map 1.0.0

How can I fix this problem?
