clBuildProgram returns CL_BUILD_PROGRAM_FAILURE, but no error occured

My program runs well on my machine. A user is getting strange error and currently I have no idea how to debug.

clBuildProgram returns -11 which indicates CL_BUILD_PROGRAM_FAILURE.

Call clGetProgramBuildInfo with CL_PROGRAM_BUILD_STATUS, it returns CL_SUCCESS and the build status is CL_BUILD_SUCCESS.

Call clGetProgramBuildInfo with CL_PROGRAM_BUILD_LOG, it returns CL_SUCCESS and the log is pasted below: 

Compilation started

Compilation done
Linking started
Linking done
Device build started
Device build done
Kernel <sim_iterate> was not vectorized
Done.

As the build log says, compilation & linking are done without any error. So what could be the problem?

The device is Intel(R) Core(TM) i3-3240 CPU @ 3.40GHz.

I fixed the issue. The parameters of clBuildProgram is not correct.

// Before:
clBuildProgram(program, 0, 0, "-cl-single-precision-constant -cl-denorms-are-zero -cl-fast-relaxed-math", 0, 0)
// After:
clBuildProgram(program, 1, &device, "-cl-single-precision-constant -cl-denorms-are-zero -cl-fast-relaxed-math", 0, 0)
