[mapserver-users] MapServer crash with WFS GetFeature request using multiple typenames

[Dejan Gambin]

Hi,

I have a serious issue usng MapServer WFS in making GetFeature request using multiple typenames. Here is the example post request:

[Mon Nov 14 09:16:06 2011].666863 msWFSParseRequest(): WFS post request: <wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs" service="WFS" version="1.1.0" maxFeatures="10" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><wfs:Query typeName="ms:ppu_sportska" srsName="EPSG:900913" xmlns:ms="http://www.openplans.org/topp"><ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"><ogc:BBOX><ogc:PropertyName>msGeometry</ogc:PropertyName><gml:Envelope xmlns:gml="http://www.opengis.net/gml" srsName="EPSG:900913"><gml:lowerCorner>1533843.3519844 5619282.0492426</gml:lowerCorner><gml:upperCorner>1533938.8982697 5619377.595528</gml:upperCorner></gml:Envelope></ogc:BBOX></ogc:Filter></wfs:Query><wfs:Query typeName="ms:ppu_turisticka" srsName="EPSG:900913" xmlns:ms="http://www.openplans.org/topp"><ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"><ogc:BBOX><ogc:PropertyName>msGeometry</ogc:PropertyName><gml:Envelope xmlns:gml="http://www.opengis.net/gml" srsName="EPSG:900913"><gml:lowerCorner>1533843.3519844 5619282.0492426</gml:lowerCorner><gml:upperCorner>1533938.8982697 5619377.595528</gml:upperCorner></gml:Envelope></ogc:BBOX></ogc:Filter></wfs:Query></wfs:GetFeature>
[Mon Nov 14 09:16:06 2011].683317 msQueryByFilter(): Search returned no results. No matching record(s) found.

It is using 2 typenames: "ms:ppu_sportska" and "ms:ppu_turisticka". Seems like no results were found but there are bunch of errors in apache log file, like:

Sometimes the error was starting with:

[Mon Nov 14 08:25:06 2011] [error] [client 83.131.213.54] *** glibc detected *** /usr/lib/cgi-bin/mapserv61: munmap_chunk(): invalid pointer: 0x000000000273ca80 ***, referer: http://www.coin.hr/coingis/demo.html

NOTE: Making individual requests to those typenames works OK

I would appreciate any help since I am pretty stucked with this. Should I report it as a bug?

Thanks very much

regards, dejan
