Segment error (core dumped)

[Win7ery]

Why is it that when using streampot data set, a sktch file can be generated when running analyzer with base and stream data at graph id 0, but an error can be generated when running analyzer with base and stream data at graph id 1
I use the following command

bin/unicorn/main filetype edgelist niters 10000 base ../base_data/streamspot_1 stream ../stream_data/streamspot_1 sketch ../sketch_data/train/streamspot_1

The following error occurred
