Segmentation fault

I just installed synce4l in a beaglebone ai.

When running with a basic conf file as: sudo ./synce4l -f ./configs/synce4l.cfg -m

The outputs says:

synce4l[385.064]: [synce4l] created synce1
synce4l[385.064]: [synce4l] device init synce1 addr 0xaaab15b788b0
synce4l[385.064]: [synce4l] config item (null).smc_socket_path is '/tmp/synce4l_socket'
synce4l[385.064]: [synce4l] set thread stack failed for synce_manager err=22
synce4l[385.064]: [synce4l] synce_clock_destroy
Segmentation fault

any help is welcome
