Floating point exception (core dumped) caused by OPTIONAL MATCH

[joyemang33]

Hi here! When I test Kuzu with a query containing OPTIONAL MATCH, it raises a "Floating point exception (core dumped)" and directly lets my Python client crash.

Here is a reduced test case to reproduce the case:

MATCH (n1)<-[]-(n1)-[]->(n2) OPTIONAL MATCH (n2)-[]-(n2)-[]->(n1)-[]->(n1), (n2)-[]-(n1)-[]-(n1)-[]-(n1) RETURN COUNT (*)

The graph data can be found here.

Thank you very much for the time to investigate it!

Best regards, Qiuyang
