Possible Memory leak in OSPF: new route node

[ryndia]

Hello, while investigating some stack trace for memory leak, I came across stack trace such as below repeating, I suppose this is a false positive. However, to be sure, I would like to have a confirmation if this is a false positive memory leak generated by asan.
