错误描述：

oracle 10.2.0.4 64bit

redhat5.6 64bit

在创建函数完成后调用直接报错：

Errors in file /opt/oracle/admin/kebao/udump/kebao_ora_26334.trc:
ORA-07445: exception encountered: core dump [_intel_fast_memcpy.A()+10] [SIGSEGV] [Address not mapped to object] [0x000000000] [] []

SESSION会话也直接中断。

[@more@]

通过定义typetype bodyfunction后通过SQL调用新声明的function函数，会话直接关闭，通过查看alert文件发现报以下错误：

Errors in file /opt/oracle/admin/kebao/udump/kebao_ora_26334.trc:
ORA-07445: exception encountered: core dump [_intel_fast_memcpy.A()+10] [SIGSEGV] [Address not mapped to object] [0x000000000] [] []

通过检查发现在type里面生成的返回值类型是CLOB的，而我的FUNCTION里面返回的是VARCHAR2的，最终导致错误的发生。
