According to NOTE in strtoul(3), the errno must be zeroed before strtoul()
is called. Zero the errno. The NOTE reads as such:
Since strtoul() can legitimately return 0 or ULONG_MAX (ULLONG_MAX for
  strtoull()) on both success and failure, the calling program should set
  errno  to  0  before the call, and then determine if an error occurred
  by checking whether errno has a nonzero value after the call.
This issue was detected on Fedora 19 with glibc 2.17 .
