I don't see anything in the ANSI C specification that would lead me to believe
that the above program's use of strtok is well defined.  Therefore the core
dumping behavior is just as acceptable as behavior that doesn't crash.

If you would like my detailed interpretation of ANSI/ISO 9899:1990 on this
matter, I'd be delighted to bore you to tears. ;)
