401100 - Possible leak in testThreadLockingBehavior.

Status: NEW

(NSS :: Libraries, defect, P3)

Description

[Slavomir Katuscak]

Function testThreadLockingBehavior is part of sqlite and is used to test if different threads can override each others locks. It creates 2 threads (pthread_create) and waits for their termination (pthread_join). Valgrind detects some possible leak there, seems that problem is in GLIBC.

OS version: Red Hat Enterprise Linux AS release 4 (Nahant Update 4)
