在Oracle 11g2 XE中编译PL / SQL函数有时会导致ORA-00600：内部错误

ORA-00600: internal error code,arguments: [17285],[0x318FDE2C],[1],[0x273F1C60],[],[]
00600. 00000 -  "internal error code,arguments: [%s],[%s],[%s]"
*Cause:    This is the generic internal error number for Oracle program
       exceptions.  This inDicates that a process has encountered an
       exceptional condition.
*Action:   Report as a BUG - the first argument is thE internal error number

断开连接并重新连接到Oracle和函数编译确定感到疯狂……

谷歌搜索错误代码和参数给了我这个

我的函数返回一个自定义的表格类型.大多数功能代码遗漏了……

CREATE TYPE t_solexp_row AS OBjeCT (
obj         VARCHAR(30),dt          DATE,param       VARCHAR(30),param_ID    numbER,val         numbER,change_time timestAMP
);
/

CREATE TYPE t_solexp_tab IS table OF t_solexp_row;
/

CREATE OR replaCE FUNCTION get_solexp_tab(p_start_date IN DATE,p_END_DATE IN DATE) RETURN t_solexp_tab PIPEliNED AS
BEGIN
    ...
    LOOP
        PIPE ROW(t_solexp_row(...,...,...);
    END LOOP;
    ...
    RETURN;
END;
/

任何可能导致这种行为的想法？
