reserving to much memory inPolygon::GetCoordinates

Reported by: jaapdekker Owned by: strk
Priority: major Milestone:
Component: Default Version: 3.0.3
Severity: Unassigned Keywords:


A length error exception is thrown when Polygon.GetCoordinates() is called with a polygon(sea area around Scotland) with 1396535 coordinates where the shell has size 411057 and that contains 7998 holes (Islands in the sea) the error is caused in Polygon.cpp where a reserve is done with the wrong size the error is on line 123 in Polygon.cpp



  • reserve space in the vector as if all holes have the same
  • amount of points. Holes usually have less, so this should
  • be a good compromise */


causing 3,287,633,886 Coordinates to be allocated
