Segment fault

[sunce4t]

I pulled down the code of Dash from github and change the workload with the one we generated ourselves, I ran into a segment fault when I run concurr_search after inserting 50 million data, and when I located it with gdb, I found that it happened in this line：
SSE_CMP8(*curr_FingerArray, meta_hash);、
Do you know what caused this problem?
Thanks！

I've had this issue before when I ran the delete method on a workload generated by dash
