Parallelization segfault knn

[Josipmrden]

Description

This example fails with SIGSEGV on parallelization, not sure why

storage mode IN_MEMORY_ANALYTICAL;
CREATE INDEX ON :Node;
CREATE INDEX ON :Node(id);
unwind range(1, 100000) as x create (:Node {id: x, embedding: [i in range(1, 1000) | i * 0.001]});

create snapshot;

match (n)
with collect(n) as nds
with project(nds, []) as graph
call knn.get(graph, {nodeProperties: "embedding", topK: 5, randomSeed: 42, concurrency: 10})
yield node, neighbour, similarity
return count(*);
