I just spent the last two hours chasing this error down, here's what the problem was for me:
I was using my class definition to allocation my GUI objects, here's a simple example to illustrate (this probably won't compile):
class app : public QObject
{
Q_OBJECT
public:
app();
ListView list;
ImageView img;
} Then I was adding these objects (list, img) list this:
container->add(&list);
container->add(&img);
class app : public QObject
{
Q_OBJECT
public:
app();
ListView *list;
ImageView *img;
}
....
list = new ListView();
img = new ImageView();
container->add(list);
container->add(img);
When I'd shutdown the application I'd get the "free malloc object" error message.
By switching to definiting object pointers in the class definition and instantiating the objects with the new operator in the code before using the object I managed to avoid the shutdown error messages.
I'd love to hear a technical explanation as to why this is happening...
I certainly hope this helps avoid some tedius debugging for others.
Cheers,
Eric
