mapserv segfaults trying to get the query results of a native oracle spatial data source

[Nicol Hermann]

Dear list,

I want to use the query function of the native Oracle Spatial support
(INPUT=ORACLESPATIAL) from mapserver 4.4.2.
Displaying the image is no problem but when try to get the query results
mapserver crashes with a segmentation fault.

Here is what i try to do:

for($j = 0;$j < $Layer->getNumResults(); $j++) {
  $oRes = $Layer->getResult($j);
  $shpobj = $Layer->getShape($oRes->tileindex,$oRes->shapeindex); // <-
Line which causes the Segmentation fault
  $shpobj->free();
}

Is this a bug or do i have to change something?
My system is:
Debian sarge, mapserver 4.4.2 (php Mapscript), oracle 10g

Attached you find the output of gdb.

Any help are welcome
Nicol
