PLS-00801 error during compile for debug

Question

Hi,
I am working as an oracle consultant, hired by an insurance company to rewrite some stuf they made...
They are using a lot of procedures with nested functions/procedures instead of packages :-(
Something strange happens though. if you have a procedure with a global cursor declaration, used as a parameterrowtype in a nested function/procedure, the source will not compile to debug (error PLS-00801), unless you delare a global rowtype of that cursor. I pasted some test source within this e-mail where the error is reproducable.
If the commented line ' -- rg_tst cg_tst%rowtype;' is enabled, the procedure will compile. when its commented, it will compile normally, but NOT with debug option...
Anyone familiar with this prob?
thanx,

Test-source
CREATE OR REPLACE PROCEDURE p_debug_test
AS
cn_max_date CONSTANT DATE := TO_DATE('12/31/2005','MM/DD/YYYY');
CURSOR cg_tst( b_param1 NUMBER )
IS
SELECT ADD_MONTHS(TRUNC(SYSDATE), b_param1) tst_date
, USER tst_user
FROM dual;
-- rg_tst cg_tst%rowtype;
FUNCTION f_date_is_valid( i_cp_tst IN cg_tst%ROWTYPE
, i_max_date IN DATE
) RETURN BOOLEAN
IS
BEGIN
RETURN (i_cp_tst.tst_date <= i_max_date);
END;
BEGIN
FOR rg_tst IN cg_tst( 6 )
LOOP
IF f_date_is_valid( rg_tst, cn_max_date )
THEN
DBMS_OUTPUT.PUT_LINE( 'Yep1' );
END IF;
END LOOP;
END;

Fundamentally it means the database connection has been lost, but they may be an underlying error.
Try the following to give yourself more chance of seeing the underlying error.
1. Run sqldeveloper from <sqldev>\sqldeveloper\bin\sqldeveloper.exe. This will leave a console window open.
2. If the problem occurs, look for error messages in the console.
Can you compile other procedures for debug without the error? Try creating a minimalist for testing.
