Interesting, does this reproduce in a test case?

I see why the Negative flag should be cleared (0x22d0e560 isn't negative), but have no idea why is the Zero flag set? this is obviously not zero

indeed not able to replicate in test or silicone, hold on as it could be a gdbdiff bug.

Ok, so I'm closing it for now. Thanks for reporting!
