mhi, big god my CuAssembler raise exception when I test the "TestData" my nvcc is 11.3, and my arch is sm_86 it throw following exception when I executed "make hack":

it will be ok when I change arch to sm_60/sm_75。 it will throw above exceptions if I change arch to sm_80/86 but, my real hardware is sm_86, so, I cannot pass these exceptions. I don't know how to fix this trouble, would you like to help me to fix this trouble? or, would you like to tell me the reason?
