As this was not properly applied to vendor/libarchive, should the attached patch be applied? I was confused until I seen that r248664 was a direct co= mmit to head without the MFV the other patches have taken. I haven't dug into the impact yet past this as this was the last issue I ca= me across and I've already added it to the port.
