ORA-01480 aborts index creation/syncronization

Question

I have a intermedia index and I have got an error creating the
index.
I you run this script, you will see the problem:
drop table test_ferran;
create table test_ferran (id number primary key, txt clob);
create index ctx_test_ferran
on test_ferran(txt) indextype is ctxsys.context
parameters ('nopopulate section group
ctxsys.auto_section_group');
insert into test_ferran values(1,
'<bbb
b<ccccccccccccccccccccccccccccccccc<ddddddddddddddddddddddddd
<e>'
commit;
begin
ctx_ddl.sync_index('CTX_TEST_FERRAN');
end;
ORA-20000: Error d'interMedia Text:
DRG-50857: oracle error in dreii0fsh
ORA-01480: manca el carScter nul a la cua de la cadena STR
ORA-06512: a "CTXSYS.DRUE", line 126
ORA-06512: a "CTXSYS.CTX_DDL", line 1298
ORA-06512: a line 2
In this other case (just adding a space) there is no problem:
drop table test_ferran;
create table test_ferran (id number primary key, txt clob);
create index ctx_test_ferran
on test_ferran(txt) indextype is ctxsys.context
parameters ('nopopulate section group
ctxsys.auto_section_group');
insert into test_ferran values(1,
'<bbb b<cc
ccccccccccccccccccccccccccccccc<ddddddddddddddddddddddddd <e>'
commit;
begin
ctx_ddl.sync_index('CTX_TEST_FERRAN');
end;
The error is not reported in ctx_errors. Oracle just abort the
index creation,
why?
.

Just tried your test on 9i and works. Which db/platform are you
using?
SQL> create index ctx_test_ferran
on test_ferran(txt) indextype is ctxsys.context 2
3 parameters ('nopopulate section group
ctxsys.auto_section_group');
Index created.
SQL> insert into test_ferran values(1,
'<bbb 2
3
b<ccccccccccccccccccccccccccccccccc<ddddddddddddddddddddddddd
4 <e>');
1 row created.
SQL> commit;
Commit complete.
SQL> exec ctx_ddl.sync_index('CTX_TEST_FERRAN');
PL/SQL procedure successfully completed.
