Thanks for looking at it. I have to patch a couple more places to change ParGCCardsPerStrideChunk to size_t (but I agree that this is the right type for it). Do you mind if I leave it as intx for now (I’ll change everything else to size_t) and do that as a separate change?

You could use size_t too for some time now if it fits better.
