If you look at the size of the WINTRUST_FILE_INFO structure the app passed in: cbStruct -> 12 bytes. That means the subject GUID member is not included and the "0x2c" ptr data most likely belongs to something different.
Ahhhhh. So obvious. I'm embarrassed it escaped my notice, and flattered that you thought this was interesting enough to look into. I'll try to get to this, but certainly wouldn't object to someone else having a go: Anastasius's suggestion looks spot on to me, and the fix looks easy.
