Example error

[crankler]

Hi, when I download the example and try to test ILCC_sample_perspective_data,
I can finish the process command of "from ILCC import img_corners_est" and "from ILCC import pcd_corners_est", but when I input "LM_opt.cal_ext_paras()", there shows

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

and I find the error locate in :

transformation = pyopengv.absolute_pose_upnp(img_bearing_vectors,pcd_bearing_vectors)[0]

I've installed the opengv package and can import opengv without error,
can you tell me how to fix this error? thank you!
