string拷贝构造函数出异常，求帮助？

gdb显示堆栈如下：


#0  0xffffe410 in __kernel_vsyscall ()

系统环境：
# uname -a
Linux linux-t1vq 2.6.16.60-0.54.5-smp #1 SMP Fri Sep 4 01:28:03 UTC 2009 i686 i686 i386 GNU/Linux

其中 str值为 “/”,因为我使用gdb打印出来，显示如下;

(gdb) p  str
$12 = (
    const string&) @0xbf8b45d4: {<std::basic_string<char, std::char_traits<char>, std::allocator<char> >> = "/", <No data fields>}

还不如给代码

今晚去你家

把代码贴出来看看
