Everyone, please upvote my related question on StackOverflow:
The bug was always present in WinSCP. But until the WinSCP 5.0.8, with its "Dynamic base address" executable flag set (Windows 8 certification requirement), the bug happening was not plausible.
While the fixed versions no longer gradually exhaust system resources, they cannot recover resources exhausted by previous buggy versions. So it's still necessary to restart affected machine to recover the system.
