Bug #: 52337
Summary: memory hole
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: critical
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: xiaoyua...@yeah.net
#include<iostream>
#include<stdio.h>
typedef char**(*(*v[4])(int*p[],float (*f)(int a[])))[][6];
class e{v i,a,b;public:int get();friend int g();}ai;
int e::get(){long h1,h2,h3;h1=(long)&i;h2=(long)&a;h3=(long)&b;
printf("%p\n%p %lx\n%p %lx\noriginal pointer is:",i,a,h2-h1,b,h3-h2);
std::cout<<&i<<std::endl;return 0;}int g(){return ai.get();}
class pgabstract{v i,a,b;public:int get(){return vget();}
int(*p)();virtual void t()=0;
int vget();}*m[4];int pgabstract::vget(){
long h1,h2,h3;h1=(long)&i;h2=(long)&a;h3=(long)&b;
printf("%p\n%p %lx\n%p %lx\noriginal pointer is:",i,a,h2-h1,b,h3-h2);
std::cout<<&i<<std::endl;return 0;}
main(){m[3]=(pgabstract*)&ai;m[3]->get();}
in the code i sure port in a class abstract
like class a{int i;virtual void t()=0;}; i sure i is circle and class typedef a
is not a inheritance.in code anywhere i donnt invite the value of class a
ai.assert
but i assert faile compile donnt alert me to memory hole i sure through out.
i alarm the name of class a privilage memory hole. it is concept. alert must!
