It looks like an easy problem, it has a trove of information on it and Bryce Boe even has a two line solution for it. However, his program does not handle improper intersections, i.e. when one end of one of the segments lies on the other line. Since a point lying on the line does not make triangles with different orientations (since it has zero area), his program does not count it as an intersection.
The highest voted answer on the stack overflow question needs special care while handling vertical lines (And it is general outline for a solution, not actual code).
Now there are multiple methods of correcting these problems, and this is one of them:
Use this function to test the implementation:
