OALL8 is in an inconsitent state

Question

I am having a problem with a sql query, that i execute through JDBC. I get a SQLJ exception with the message "OALL8 is in an inconsitent state"
It only happens when I execute this particular query. All the other queries i execute, return normally.
Can anyone help me with this problem?
Further info:
On my Oracle 11G server i get the following message in my alert log:
Mon Aug 17 12:48:38 2009
Exception \[type: ACCESS_VIOLATION, UNABLE_TO_READ\] \[ADDR:0x2ED94D98\] \[PC:0x7B11692, kggfaDoKghAlloc()+122\]

from the trace fil i find that the SQL i am executing looks like this:
  WITH services AS (
    SELECT y.pk, y.guid
      FROM actions y
     WHERE y.personlink = :1
       AND (y.endtime >= :2  OR y.endtime IS NULL)
       AND y.id LIKE 'CLINICAL.ACTION%'
       AND NOT (y.status = 4)
       AND (
             ( y.decisiontime <= :3
               AND NOT y.id = 'CLINICAL.ACTION.MEDICATION'
             OR
               y.id = 'CLINICAL.ACTION.FOLDER'
  SELECT y.pk pk FROM services y
  UNION
  SELECT folder.pk FROM Actions folder WHERE folder.guid IN (SELECT folderLnk.FROMLINK FROM links folderLnk
    START WITH
      folderLnk.TOLINK in (SELECT y.GUID FROM services y) AND
      folderLnk.ID = 'CLINICAL.ACTION.FOLDER.CONTENTS'
    CONNECT BY PRIOR folderLnk.FROMLINK = folderLnk.TOLINK and folderLnk.ID = 'CLINICAL.ACTION.FOLDER.CONTENTS')
  UNION
  SELECT aps.pk pk
    FROM services y, links l, actions aps
   WHERE l.fromlink = y.guid
     AND (   l.id = 'CLINICAL.ACTION.PLANNING'
          OR l.id = 'CLINICAL.ACTION.STATUS.HISTORY')

Hello damorgan,
The firs select statement only return one value, the primary key of y. The select which does in fact return two values is the one inside the "WITH x AS SELECT..." statement. The query actually works on another Oracle 11G DB server.
I just found out that any change in the phrasing of the statement, even introducing an extra new line character, makes the problem go away.
A collegue of mine suggests that the server has somehow cached the statement and done some kind of unhealthy optimization of its execution plan.
The oracle error code give in the alert log apparently indicates an internal oracle error. I will try creating a service request on metalink, as soon as I can get access.
Best regards
Søren
