[mapserver-users] queryUsingPoint seg fault on demo maps

[Jim Burnett]

OK, I switched to GD1.8.4 and MapServer/Script  3.5  (nightly build)
Instead of a complete crash, I get this. ( better then complete crash)

Warning: MapServer Error in msQueryByPoint(): No matching record(s) found.
in /drives/storage1/homes/htdocs/maptest/php/test.php on line 71


here is my code:
I am using the shape file and map file provided in the demo, i just renamed
it.


if ( $map_x && $map_y ) {
 $mapObj = ms_newMapObj("/home/htdocs/maptest/romney.map");

 $ptClicked = ms_newPointObj();
 $ptClicked->setXY($x,$y);
 print $ptClicked . "<br>\n";

#$layerObj = $mapObj->getLayerByName("lakes");
$queryObj = $mapObj->queryByPoint( $ptClicked,MS_MULTIPLE,-1 );

 #$qObj = ms_newQueryObj($layerObj);
 #$qObj->setexpression("/./");


#$queryObj = $layerObj->queryByPoint( $ptClicked,MS_MULTIPLE,3 );

 print  "click X Y:" . $map_x . " x " . $map_y . "<br>\n";
 print "mapObj->name:" .  $mapObj->name . "<br>\n";
 print "mapObj->numlayers:" . $mapObj->numlayers . "<br>\n";
 print "layerObj->numqueries:" . $layerObj->numqueries . "<br>\n";
 print "layerObj->other:" . $layerObj->queryitem . "<br>\n";
 print "queryObj->numresults:" . $queryObj->numresults . "<br>\n";
 print "queryObj:" . $queryObj . "<br>\n";
}
