--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
You access an out of bounds for the array dhcp_rx_options_given in the while
statement:

  while((dhcp_rx_options_given[8 + n] != 0) && (n < 2)) {


Swap around the two expressions so you check to make sure n is less than 2
before doing the array access. that is:

  while((n < 2) && (dhcp_rx_options_given[8 + n] != 0)) {
