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

If you are using the C instead of C++:

err = clBuildProgram(program, 0, NULL, NULL, NULL, NULL); 

////////////////Add the following lines to see the log file///////////

if (err != CL_SUCCESS) {
char *buff_erro;
cl_int errcode;
size_t build_log_len;
errcode = clGetProgramBuildInfo(program, devices[0], CL_PROGRAM_BUILD_LOG, 0, NULL, &build_log_len);
if (errcode) {
            printf("clGetProgramBuildInfo failed at line %d\n", __LINE__);
            exit(-1);
        }

    buff_erro = malloc(build_log_len);
    if (!buff_erro) {
        printf("malloc failed at line %d\n", __LINE__);
        exit(-2);
    }

    errcode = clGetProgramBuildInfo(program, devices[0], CL_PROGRAM_BUILD_LOG, build_log_len, buff_erro, NULL);
    if (errcode) {
        printf("clGetProgramBuildInfo failed at line %d\n", __LINE__);
        exit(-3);
    }

    fprintf(stderr,"Build log: \n%s\n", buff_erro); //Be careful with  the fprint
    free(buff_erro);
    fprintf(stderr,"clBuildProgram failed\n");
    exit(EXIT_FAILURE);
}
