Libcrafter generates bad Checksum with IP OPTION length of 40 bytes

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Set IP option, and generate 38 byte payload
          unsigned char opt_arr[40];
          ip_opt_h.SetOption(8);
          ip_opt_h.SetPayload(opt_arr,38);


here is the IP header of the pkt with bad Checksum,

#        4f 00 02 fe 00 00 40 00 40 06 5c 20 be 6b d2 d3 
#    41 94 2d 2c 88 28 d8 54 c4 05 b4 67 ea 22 b5 b3 
#    2b ac 3e 11 5e 2a 6c 63 69 8e e2 c1 ac db b2 91 
#    73 f3 38 aa 6b 10 fe 30 15 b3 97 ff
