Spatial query results in core dump

Question

Following query leads to a core dump error. I only can get the first 45 rows.
ksedmp: internal or fatal error
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [_kokekd2m+43] [PC:0x13A71A3] [ADDR:0x65CECD14] [UNABLE_TO_READ] []
SELECT geom.link_id, geom.link
FROM state
JOIN link ON state.state_id=link.state_id
JOIN geom ON link.link_id=geom.link_id
WHERE MDSYS.SDO_FILTER(link, MDSYS.SDO_GEOMETRY(2003, 8307, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 3), MDSYS.SDO_ORDINATE_ARRAY(-118, 36, -114, 40)), 'querytype=WINDOW') = 'TRUE'
AND state.class=1
If i change the select clause to:
SELECT count(geom.link_id) ...
it works fine.
Does anyone has similar experience?

Hi,
I'm not sure this is exactly relevant but there used to be a bug (certainly in 9i) wherby if you had a SDO_GEOMETRY column in a result set (or subquery) that was being subjected to a sort operation and there were more than a certain figure (32K rings a bell although I could be wrong on that) of rows then it would die. The sort wasn't necessarily a "user" sort - it could be being performed by the database to speed up a join or group by.
Which version of the DB are you using?
If you just try this :
SELECT geom.link_id
FROM state
JOIN link ON state.state_id=link.state_id
JOIN geom ON link.link_id=geom.link_id
WHERE MDSYS.SDO_FILTER(link, MDSYS.SDO_GEOMETRY(2003, 8307, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 3), MDSYS.SDO_ORDINATE_ARRAY(-118, 36, -114, 40)), 'querytype=WINDOW') = 'TRUE'
AND state.class=1
i.e just remove the geometry column from the results set, does this work?
If it does than you may need to wrap this (working) query up as a subselect and join back to your original table to get the geometry "back" if you need it.....
