Hey folks,
I was misunderstanding the concept of heap and stack variables. I have made:
engine.addImageProvider("pictures", new ImageProvider());
The problem is now solved!
Thanks for your help!
Regards,
Nuno

you still have a double delete in this case. A first delete when
QQmlApplicationEngine is destroyed at the end of the main, and a second
delete when the static is deleted.

Sérgio,
Thanks for your reply.
I have tried the following:
ImageProvider imageProvider;
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
Controller controller;
QQmlApplicationEngine engine;
engine.rootContext()->setContextProperty("controller", &controller)
Hi Nuno,
The docs for QQmlEngine::addImageProvider() say: "The QQmlEngine takes
ownership of provider".
So QQmlEngine::removeImageProvider() is calling free() on stack
variable, hence it complains that address wasn't heap allocated.
Create it on the heap as suggested by Jean-Michaël.

Jean,
This is the main context. It will not get out until app.exec() terminates

This is the main context. It will not get out until app.exec() terminates.
That’s why I’m connecting to aboutToQuit signal in order to remove the provider
from the Qml engine.
I had the provider instantiated inside the controller but I was having this
problem already, therefore my effor
Shouldn't you allocate your ImageProvider on the heap or at least ensure
that it survives during the whole execution ? here it will be deleted by
the end of your function

Hi,
Yesterday I have used for the first time a QQuickImageProvider but I’m having
problems because now the app crashes when I terminate it.
Tried to do the following in order to avoid the crash but it is crashing anyway:
ImageProvider imageProvider;
engine.addImageProvider("pictures", &imagePro
