[postgis-users] postgres crash on invalid gml in geomfromgml

[Willy-Bas Loos]

Hi,

PostgreSQL crashes when i send it an 'invalid' gml in st_geomfromgml(().
In fact the gml is not invalid AFAIK, but it might be considered a
GML-document instead of a GML-fragment.
The server is supposed to throw an error when that happens, but it crashes.

query:
select st_geomfromgml('<OriginalGeometry gml:id="1" srsDimension="2"
srsName="EPSG:28992" xsi:type="gml:PointType"
xmlns:ns="http://willy-bas.nl/yes/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:gml="http://www.opengis.net/gml/3.2">
  <gml:Point>
    <gml:posList>600000 300000</gml:posList>
  </gml:Point>
</OriginalGeometry>')

Response:
server closed the connection unexpectedly
	This probably means the server terminated abnormally
	before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
