Data race condition

The value of the shared data will be determined by the interleaving of thread execution. Thread shared data is accessed without holding an appropriate lock, possibly causing a race condition

Elsewhere, "mongo::WiredTigerBackup.cursor" is written to with "WiredTigerBackup.wtBackupDupCursorMutex" held 2 out of 2 times (1 of these accesses strongly imply that it is necessary).
