     Type:  defect               |      Status:  new          
 Priority:  medium               |   Milestone:  PostGIS 1.5.4
Component:  postgis              |     Version:  1.5.X        
 Keywords:  gml, invalid, crash  |  
---------------------------------+------------------------------------------
 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.
