the following test creates error 00600:

DROP TYPE TEST.TSSTRINGLIST
/
CREATE OR REPLACE type TSStringList is table of varchar2(32000)
/

declare
sl TSStringList := TSStringList();
res TSStringList := TSStringList();
begin
sl.extend(1);
sl(sl.count) := 'hallo 1';
sl.extend(2);
sl(sl.count) := 'hallo 2';
sl.extend(3);
sl(sl.count) := 'hello 3';

select column_value bulk collect into res from table(sl);
end;

---------------------------------------------------------------------------

up to varchar2 (24000) or with NLS_LENGTH_SEMANTICS database:Byte instance:byte session:byte it works without problems;

whats wrong ??
