#732: BufferOp(0.0) makes the attached polygon "miss"!
-------------------------+---------------------------
Reporter: jiangdaidai | Owner: geos-devel@…

Priority: major | Milestone: 3.4.3
Component: Default | Version: 3.4.2
Severity: Critical | Resolution:
Keywords: BufferOp |

Comment (by jiangdaidai):
I find the reason: my polygon self-intersectes and is_ccw(my polygon)
makes the key unexpected performance. During the learning of GEOS, I think
there may be one bug :
SegmentIntersector.cpp Line 114, according to the algorithm logical,
int maxSegIndex=e0->getNumPoints()-1; -->
int maxSegIndex=e0->getNumPoints()-2;
