hi yi:
I find this cause by your ICD version.
In you ICD version, the clCreateContext failed to check
cl_context_properties invalid_platform_context_properties[] = {
CL_CONTEXT_PLATFORM, (cl_context_properties)NULL,
};
casues this crash.
And new version ICD has fixed this version.
Please update the ICD to at least 2.1.3
