Hopefully, that will convince Coverity that the result of dereferencing those pointers will have a value between 0x00 and 0xff, and therefore that shifting that result right by 4 bits will yield a value between 0x0 and 0xf, and therefore that this result can safely be used as an index into the 16-element hex[] array. I guess Coverity wants us to realize that there really *are* C implementations out there with non-8-bit char and unsigned char values, even though getting tcpdump to work on them will probably be a highly entertaining exercise (not to mention that the only one I know of that's actually being *used* are the Unisys Clearpath Dorado series, and they're one's complement, which is yet *another* place where the port could be entertaining...).
