Magick++ Memory Leak with Corrupted JPEG Files

[zeugman]

I found memory leak in reading some jpeg files.
Valgrind output :

Code: Select all

Example of Code :

Code: Select all

#include <Magick++.h>
#include <string> 
#include <iostream>
#include <fstream>
using namespace std;
using namespace Magick;

int main(){
	Image * image;
	image = new Image("MENUsouris-naked.JPG");
	cout << "Width :" << image->baseColumns() << std::endl;
        cout << "Height :" << image->baseRows() << std::endl;
	delete image;
    return EXIT_SUCCESS;
}
