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

Hi Fernando,
thank you very much for your e-mail.
I tried the latest CVS version ($Id: maporaclespatial.c,v 1.26
2005/04/28 22:19:41 rodrigo Exp $) with the '--enable-point-z-m'
compiling flag but it did not change the situation.
Mapserver crashes when it try to access the search results with:
$shpobj = $Layer->getShape($oRes->tileindex,$oRes->shapeindex);
I also found, that nearly the hole map-object is empty when i add the
'--enable-point-z-m' compiling flag (see attached gdb output) and try to
access it with PHP Mapscript.
$map = ms_newMapObj('oracle_test_gk3.map') or die('Error.');
var_dump($map);
Removing this flag gives me the normal look.
Here is my oracle layer definition.
Yes i define a template, and no i did not define any filter parameter:
LAYER
NAME Oracle
STATUS DEFAULT
TYPE POLYGON
DEBUG ON
CONNECTIONTYPE oraclespatial
CONNECTION "user/passwd at BOX.os"
DATA "GEOMETRIE from FLURST USING SRID 82027"
PROJECTION
"init=epsg:31467"
END
CLASS
NAME gw
TEMPLATE "dummy.html"
STYLE
COLOR 192 192 192
OUTLINECOLOR 0 0 0
END
END
END
Should i open a bug on this?
Many thanks
Nicol
