    Hi Melissa,

    Thanks for the great bug report! I confirm this is an issue in the compiler back-end. From the preliminary analysis, it looks like the inliner is doing an incorrect type conversion.


    We are working towards a bug fix, and will keep you posted. In the meanwhile, a workaround would be to place __declspec(noinline) on the function that calls _mm_loadu_si64. Please get back to us if you need any further information.

    Thanks,

    Amit Sabne
