BlackmagicRAW SDK extracted frame has strange colors

I started building a .braw reader for Nuke, on Win. Got an image, but it has strange colors, skin is green for example. I tried all combinations of channel ordering, so there must be something I'm missing in raw frame processing. I used the ExtractFrame example as basis, practically unmodified, except I request decoding to RGB32F format instead of RGBAU8. Original sample code .exe produces normal colored .bmp files. Any ideas what might be the reason of this strong discoloration?

Got it working, was a channel shuffling problem afterall but high exposure in Nuke tripped me a bit from seeing it.
