Memory corruption error
« on: March 31, 2015, 12:14:31 pm »
I'm using SFML with Ubuntu 12.04.4 on and Oracle VM and compiling with QT4.8.1.

I followed this tutorial https://github.com/SFML/SFML/wiki/Tutorial:-Compile-and-Link-SFML-with-Qt-Creator for downloading and building SFML.

I've had success in running a project, but since a VM crash I started running into issues. I've since re-downloaded and re-built SFML from scratch a few times without success. I'm not sure if the issue is with SFML or if it's my VM but I'm not sure where else to post.


Entry point for application
//main.cpp

#include <iostream>
#include <SFML/Graphics.hpp>
#include "frame.h"

int main()
{

    Frame frame(sf::VideoMode(800,600,32), "Test");
    frame.Run();
    return 0;

}

 

Frame header

//Frame.h

#ifndef FRAME_H
#define FRAME_H

#include <SFML/Graphics.hpp>

class Frame
{
public:
    Frame(sf::VideoMode, std::string, float frameRate_ = 120.0f);
    void Run();
    ~Frame(){}
private:
    sf::RenderWindow *window;
    sf::RectangleShape background;
    sf::RectangleShape hand;
};

#endif // FRAME_H


 

Frame class
//Frame.cpp

#include "frame.h"
#include <iostream>
#include "SFML/Graphics.hpp"

Frame::Frame(sf::VideoMode screen, std::string title, float frameRate_)
{
    sf::Texture *texture = new sf::Texture();
    texture->loadFromFile("Images/cash_back.png");
    texture->setSmooth(true);
    background.setTexture(texture);
    background.setPosition(sf::Vector2f(0.0f,0.0f));
    background.setSize(sf::Vector2f(800.0f,600.0f));
    hand.setFillColor(sf::Color::Green);

    window = new sf::RenderWindow(screen, title);
    window->setFramerateLimit(frameRate_);
    window->draw(background);

}

void Frame::Run()
{
    bool running = true;
    sf::Event ev;
    while(running)
    {
        while(window->pollEvent(ev))
        {
            if(ev.type == sf::Event::Closed)
            {
                running = false;
            }
        }
        window->setActive();
    }
    std::cout<<"bingo"<<std::endl;
}

 


The initial error message I received after running
./Test
was

*** glibc detected *** ./Test: malloc(): memory corruption: 0x00000000025fa780 ***

So I downloaded Valgrind and tried running
valgrind --track-origins=yes ./Test
 

and the output was:

So is it an issue with SFML? Is my VM corrupt? The VM has access to 12gb of ram and has a dynamically allocated hard disk so I dont think it's a lack of memory issue. I'm not exactly new to SFML but I'm somewhat new to QT and Linux.

Your help would be greatly appreciated.

I think your problem is

sf::Texture *texture = new sf::Texture();

You never destroy that texture.

Just set sf::Texture texture as a Member of Frame and I think you should be fine.

Good catch, I'm too used to having pointers cleaned up after me. After Fixing that it gives me
Unable to get joystick attribute. Could not find usb device for joystick at index 0.

I've seen something about this error before and checked to make sure my JoystickImpl and JoystickManager files were the updated ones and they are.

I'm not sure what the point of posting valgrind output is... it is known that valgrind 'detects' memory leaks within SFML.

Ah didn't realize the memory leak was normal, saw that joystick was recurring and thought it might be the root of the issue.

Thanks for your help

Normal? No, SFML doesn't leak memory, but that is hard to explain that to someone who trusts exactly what valgrind says. All memory leak detection tools have false positives.

This is my first time using Valgrind, I'm still not entirely sure what it's telling me.

I read through that link you gave me and updated the JoystickImp.cpp and .h, it seems I'm having the same issue as zwookie did initially, although I built the debug libraries and am linking statically. Do I need to rebuild the libraries with these files in my src?

Learn to use git, manually changing files from a diff isn't the way to go. Also if you use static linking please at least understand what it does and how the compile/link process works. Changing source files doesn't change compiled binaries automatically.
