Ora-01001 in procedures with ref cursor parameter after upgrade to 11.1.0.7

Question

Hi,
after upgrading from 11.1.0.6.0 to 11.1.0.7.0, I get ora-01001 in procedure calls which have a ref cursor as an out parameter.
Even a new 11.1.0.7 instance throws this error. My OS is Linux SLES10SP2.
Please see atched sample code:
CREATE OR REPLACE PACKAGE test1_pck
IS
PROCEDURE run1; -- OK on 11.1.0.6; fails on 11.1.0.7
PROCEDURE run2; -- OK on 11.1.0.6; OK on 11.1.0.7
END test1_pck;
CREATE OR REPLACE PACKAGE BODY test1_pck
IS
TYPE t_rec IS RECORD(col dual.dummy%TYPE);
TYPE t_cur IS REF CURSOR RETURN t_rec;
PROCEDURE foo1(p_cur OUT t_cur)
IS
v_sql VARCHAR2(255) := 'BEGIN OPEN :1 FOR SELECT dummy FROM dual; END;';
BEGIN
EXECUTE IMMEDIATE v_sql USING p_cur;
END foo1;
PROCEDURE foo2
IS
v_sql VARCHAR2(255) := 'BEGIN OPEN :1 FOR SELECT dummy FROM dual; END;';
v_cur t_cur;
v_rec t_rec;
BEGIN
EXECUTE IMMEDIATE v_sql USING v_cur;
LOOP
FETCH v_cur INTO v_rec;
EXIT WHEN v_cur%NOTFOUND;
CASE v_rec.col
WHEN 'X' THEN dbms_output.put_line('success');
ELSE dbms_output.put_line('error');
END CASE;
END LOOP;
END foo2;
PROCEDURE run1
IS
v_cur t_cur;
v_rec t_rec;
BEGIN
foo1(v_cur);
LOOP
FETCH v_cur INTO v_rec;
EXIT WHEN v_cur%NOTFOUND;
CASE v_rec.col
WHEN 'X' THEN dbms_output.put_line('success');
ELSE dbms_output.put_line('error');
END CASE;
END LOOP;
END run1;
PROCEDURE run2
IS
BEGIN
foo2;
END run2;
END test1_pck;
Thanks for any hints.
Regards Frank

Hi Max,
the referenced thread discusses a .Net problem. A lot of layers are involved their. My problem is a very basic problem. You get this error even if you run the test in a sql session on the server.
It would be a great help for me
a) if someone could test this package on a 11.1.0.7 database
b) if someone could test this package on a 11.2 database (is it fixed in Release2?)
c) if someone could give me hints how I could modify the procedure to make it usable for 11.1.0.7
(I already tried a lot e.g. EXECUTE IMMEDIATE v_sql USING OUT p_cur;
Thank you
Frank
