CUPTI, CUDA9.1 and sass_source_map example

Hi
I am running the CUPTI sass_source_map example under Win7/64, cuda 9.1, Titan Volta, and dev driver 388.59.
If you enable the DUMP_CUBIN symbol you will get the binary for the kernel. You can then use
nvdisasm to dump the sass.

I get the binary file. Then I type nvdisasm -b SM70 sass_source_map.cubin
I get an nvdisasm error. Unrecognized operation for functional unit ‘uC’ at address 0x00000000.

Can anyone help me diagnose this error? Given the purpose of this CUPTI example, how else are you
supposed to correlate the disassembled code back to the source code? I ran NVDISASM against the cubin
output from the compiler and the correlation didnt make sense.

By the way, I am using …
