l3_capture prints only blank lines

[a-s-m-asadujjaman]

I am getting only blank lines when running demo/L3-capture. After checking, found that it's because nsets is 0. That is l3_getSets(l3) is returning 0 at line 35 of L3-capture.c

UPDATE: Manually setting the value of nsets (e.g., 256, 2048 etc.) results in segmentation fault.
