[PATCH 4/5] oleaut32: Don't release a NULL interface in VARIANT_UserFree().

[Marvin]

Hi,

While running your changed tests on Windows, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Full results can be found at:
