Segfault in dbgen

[zingdle]

$ python util.py ssb 1 gen
SSBM (Star Schema Benchmark) Population Generator (Version 1.0.0)

Segmentation fault (core dumped)

According to this, you can just change MAXAGG_LEN from 10 to 20, which works for me.

From my experience, just use ssb-dbgen from https://github.com/eyalroz/ssb-dbgen instead of the official one.
