True! It caused me weeks of grief tracking down these triple faults!
I don't see any reason to have an intermediate "low", it just makes it harder
to piece the entire thing together.  My vote is for:
        return (uint64_t)desc->base3 << 32 |
               (uint64_t)desc->base2 << 24 |
               (uint64_t)desc->base1 << 16 |
               (uint64_t)desc->base0;

Thanks for the review. I agree, your version is much cleaner. I will 
send a v2 with this change shortly.

Best,
