bug 839327 Crash in Gcalc_operation_reducer::end_couple with ST_UNION and MULTIPOLYGONs in 5.3-gis.
When edges of a polygon coicide, it can form an pike, that is turned into a line after an operation.
In this case a former polygon point can be an end of a single line, and that case wasn't properly handled.
