fix with this code

case 'p':
         if (argv[i][2])
                arg = argv[i]+2;
         else
                arg = argv[++i]; // Passes a NULL value that breaks rangelist_parse_ports in ranges.c
                //fprintf(stderr, "%.*s: empty parameter\n", argv[0], argv[1]);
                //break;
         masscan_set_parameter(masscan, "ports", arg);

@Cnlouds please do NOT fix this way.

The correct way is pull request #246

If you fix this way, when you run 'masscan -p' you get a NULL ptr dereference. The initial fix for that issue is what caused this issue... #246 fixes both.
