hp unix coredump在最后一行return 0上
有人遇到过这种情况吗？

$ file core
core: ELF-64 core file - PA-RISC 2.0 - received SIGSEGV
$ gdb -c core
Core was generated by `SimpappClient'.
(gdb) where

Error accessing memory address 0x0: Invalid argument.

我加了些log语句发现，所有都执行成功了，就是main函数中的最后一句：return 0，给coredump了
从core文件的函数栈来看，不是在我的代码中coredump的，是系统的。

这是hp的bug吗？如果是的话，需要安装什么补丁吗？
