More likely a bug in the mesa OpenCL code. If you want functional OpenCL, you should use the ROCm OpenCL packages.
Do you mean "Mesa OpenCL is not supported/unmaintained"?
I still can't get any OpenCL application to work (even "Hello World" examples).
Mesa 18.3.4, 19.0.x - GPU hangs then resets. But judging by power consumption (hwmon, 70W - higher than usual idle power consumption) GPU continues to do something even after reset
Mesa 19.1.x, git master - GPU doesn't hang but applications themselves hang on the first clFinish. Power consumption stays higher than typical idle power again.
Building ROCm from source is a huge pain.
