In this case getline returns a zero length string. Given a zero length
string strtok will return 0 (otherwise known as NULL). I would guess that
your code assumes that a line contains at least one valid token and
therefore you end up deferencing a null pointer. But without seeing your
code its only a guess, don't be shy, POST YOUR CODE.
