hi,
I have one program runs fine on my i386 linux box but get the "glibc
detected *** corrupted double-linked list" error on the x86_64 linux
box. Please help me to figure out if it is my program's problem or the
library's problem. The libraries I am using is the boost and stl. The
original program is quite long and I shrink it short and still able to
duplicate the error. Basically, I first create a priority queue and
after several round of pop the queue the error message comes up. The
x86_64 is just installed so the packages there are most current,
comparing to those in the i386 box.
Here is the testing part:
-------------------------------------------------
#include <queue>
#include "Point2i.h"
#include "myUnit.h"
#include <boost/shared_ptr.hpp>
#include <iostream>
int main(int, char *[])
{
std::priority_queue<boost::shared_ptr<myUnit>,std: :vector<
boost::shared_ptr<myUnit, ptr_less< boost::shared_ptr<myUnit >
priorityQ;
for (int i = 0; i < 3; i++)
for (int j = 0; j < 3; j++){
boost::shared_ptr<Point2ip(new Point2i(i,j));
boost::shared_ptr<myUnitunit(new myUnit(std::rand(), p, i, j));
priorityQ.push(unit);
}
while (!priorityQ.empty()){
std::cout<<priorityQ.size()<<" "<<std::flush;
priorityQ.pop();
std::cout<<priorityQ.size()<<std::endl;
}
}
----------------------------------------------
#ifndef POINT2I_H
#define POINT2I_H
class Point2i{
public:
int x, y;
void operator=(const Point2i & p);
Point2i(int x, int y){
this->x = x;
this->y = y;
}
~Point2i();
};
#endif
---------------------------------------------------
#include "Point2i.h"
void Point2i::operator=(const Point2i &right){
this->x = right.x;
this->y = right.y;
}
Point2i::~ Point2i(){}
--------------------------------------------------
#include "myUnit.h"
myUnit::myUnit(const double delta, const shared_ptr<Point2i>& p, const
unsigned short aCount, const unsigned short bCount) {
this->delta = delta;
this->p = p;
this->aCount = aCount;
this->bCount = bCount;
}
myUnit::~myUnit(){
p.~shared_ptr();
}
-----------------------------------------------------
#define MYUNIT_H
#include "Point2i.h"
#include <boost/shared_ptr.hpp>
using namespace boost;
class myUnit {
public:
double delta;
shared_ptr<Point2ip;
unsigned short aCount, bCount;
myUnit(const double delta, const shared_ptr<Point2i>& p, const
unsigned short aCount, const unsigned short bCount);
~myUnit();
bool operator<(const myUnit & right) const {
return delta right.delta;
};
};
template <typename Pointer>
struct ptr_less{
bool operator()(const shared_ptr<myUnit& lhs, const
shared_ptr<myUnit& rhs){
return *lhs < *rhs ;
}
};
#endif
----------------------------------------------------
Here is the result from i386 machine, no error:
9 8
8 7
7 6
6 5
5 4
4 3
3 2
2 1
1 0
Here is the result from x86_64 machine with error:
9 8
8 7
7 6
6 *** glibc detected *** corrupted double-linked list:
0x00000000006d5950 ***

Thanks for your help. Have a good weekend.
