在这种情况下居然strings不出结果， 呵呵哒！

        看代码：

#include <iostream>using namespace std;class A {public:void fun1(){printf("this is a xxx1\n");}void fun2();};void A::fun2(){printf("this is a xxx2\n");}void fun3(){printf("this is a xxx3\n");}int main(){return 0;}

       看结果：

xxxxxx:~> strings a.out /lib/ld-linux.so.2SuSESuSElibpthread.so.0_Jv_RegisterClasseslibstdc++.so.6__gxx_personality_v0_ZNSt8ios_base4InitC1Ev_ZNSt8ios_base4InitD1Ev__gmon_start__libm.so.6libgcc_s.so.1libc.so.6puts__cxa_atexit_IO_stdin_used__libc_start_mainGLIBC_2.0GLIBC_2.1.3CXXABI_1.3GLIBCXX_3.4PTRh@[^_]this is a xxx3this is a xxx2

        居然没有this is a xxx1,  今天踩了这个大坑， 差不多浪费0.5小时。
