Segfault with Python version

[GoogleCodeExporter]

Following input makes Python version segfault:

points = [
    [2.10229524019, -0.760509508136],
    [2.15571376911, -0.752653842118],
    [2.00173917352, 0.294373407871],
    [1.9483206446, 0.286517741853]
]
holes = [[
    [1.9968142935, 0.0247609293562],
    [2.02104796235, 0.0283247041864],
    [2.08803526014, -0.495188920808],
    [2.06380159129, -0.498752695638]
]]

one edge of the hole is very close to contour. I'm not sure whether this input 
is correct but it should not segfault.

Sorry for the late reply.

I tested the input on the java version, tho it didn't crash the hole can't be 
handled because one point seems to be on the edge of the polygon or close 
enough to be considered on the edge. 

I have forwarded this issue to the maintainer of the Python port.

Thomas is correct; one point in the hole is close enough to the edge of the 
polygon to be considered on the edge. Holes need to be contained "inside" their 
respective polygons! 

FYI, this point set does not make the C++ version crash.... but it returns an 
incorrect result because of the invalid input; attached is a screenshot.
