Benchmark command is copied into an array in the stack. The array is BENCHMARK_ARGS items long but the command line could try to provide a longer command. Argument size is also fixed by BENCHMARK_ARG_SIZE (63 bytes of space after fitting the terminating \0 character) and user could have inputted argument longer than that.
Return error in case the benchmark command does not fit to the space allocated for it.
