Problem running with AMD CPU icd

[malakudi]

Trying to run with AMD CPU icd for some test on my Ryzen 1700X. I get the following error:

Code:

./hashcat64.bin --opencl-platform=2 -b 
hashcat (v4.0.1) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.
