clBuildProgram failed with error code -11 and without build log

Question

I have worked little bit in OpenCL now but recently \"clBuildProgram\" failed in one of my program. My code excerpt is below:

cl_program program;
program = c

I've seen this happen on OSX 10.14.6 when the OpenCL kernel source is missing the _kernel attribute tag. If both the _kernel tag and return type are missing it seems to crash the system OpenCL compiler daemon, which then takes a few seconds to restart before new kernels will compile again.
