Got Segmentation Fault

Hi, when I run

./bin/demo_reg configs/hit_ms/gem_pagor.yaml examples/data/livox/source.pcd examples/data/livox/target.pcd

I get the following error:

Stack trace (most recent call last):

Segmentation fault (Address not mapped to object [0x49])

But running this command works fine:

./bin/demo_reg configs/hit_ms/gem_3dmac.yaml examples/data/livox/source.pcd examples/data/livox/target.pcd

It seems there is something wrong with pagor?

The program seems to go wrong here: https://github.com/HKUST-Aerial-Robotics/G3Reg/blob/755d3f36cd1d941e005dbd7c055add92093e39bd/src/utils/opt_utils.cpp#L74 The GTSAM version I installed is the latest 4.2.
