libnuma numa_parse_cpustring is returning warnings inconsistently.  You have one case where numa_parse_cpustring prints an error to stderr (if you have a bit set in string that is > max cpu in cpu affinity mask) and in another case it silently drops bits.

~/tests/gdk >taskset -c 0,12 ./numaparse 1-13
libnuma: Warning: cpu argument 13 out of range

~/tests/gdk >taskset -c 0,12 ./numaparse 1-2
