Comment(by strk):

 Actually, the incremental buffer approach crashed nonetheless, with the
 known assertion failure:
 {{{
 RightmostEdgeFinder.cpp:76: void
 geos::operation::buffer::RightmostEdgeFinder::findEdge(std::vector<geos::geomgraph::DirectedEdge*,
 std::allocator<geos::geomgraph::DirectedEdge*> >*): Assertion `checked>0'
 failed.
 }}}

 That one should be fixed already in GEOS development version.
