Kùzu version

What operating system are you using?

Ubuntu 22.04

What happened?

MATCH (n1:L1:L2)-[]-(n2:L4:L5) RETURN COUNT(*)
=> 42
MATCH (n2:L4:L5)-[]-(n1:L1:L2) RETURN COUNT(*)
=> Segmentation fault (core dumped)

The graph data can be generated by the following file create.log

Hi @joyemang33 This query returns an empty result for me:

MATCH (n1:L1:L2)-[]-(n2:L4:L5) RETURN COUNT(*)
=> 42

I can't find a rel table which is from L1->L4, L1->L5, L2->L4, L2->L5. What i get from executing the create.log file is 7 rel tables: T0(FROM L5 TO L4) T1(FROM L0 TO L7) T2(FROM L3 TO L5) T3(FROM L3 TO L7) T4(FROM L0 TO L2) T5(FROM L3 TO L3) T6(FROM L3 TO L1) T7(FROM L1 TO L7) Is there a typo in your query? Thanks, Ziyi

Hi @joyemang33

Thanks, Ziyi
