Sniffit crashes on strncpy(IP,hlp2,255) in sniffit.0.3.7.c on lines 1645 and 1660, to-be-tokenized hlp string copied from optarg is a regular ipv4 address (as I checked with printf). Tested with and without optimizations. I dunno what ipv6 address string format is expected before tokenization with ":", so I can't propose solution. Problem is in hlp2=(char *)strtok(hlp,":"), where hlp2 is probably NULL when there are no ":" in hlp, so it should be checked before strncpy-ing. Next problem is "strip sniffit" in Makefile.in on line 31, I think it should be patched to make sniffit comply the FEATURES="nostrip" flag.

I can confirm the problem on amd64, but not on x86.
This is something that should be sent upstream.
