    33This case is particularly interesting/egregious, because it can be reduced to the following:
    4 
     4{{{
    55  A: LINESTRING (-57 6.939016666666666, -57.001016666666665 7.935202777777778)
    66
    77  B: LINESTRING (-57.2696825964778 7.15879416404005, -57 6.93901666666667)
    8 
     8}}}
    99By inspection these two lines do intersect.  So the line segment intersection computation is computing an incorrect answer.  Much work has been done to try and make this computation robust, but clearly there is more work to do.
