Description
Summary
The memory allocated by SceneLoader isn't released when the Scene3D it belongs to is destroyed.
What did you do?
I use a Loader to load a QML Scene3D. This scene only comprises an Entity that is filled by a SceneLoader component, which reads an OBJ file.
What did you expect to happen?
I expect the memory allocated by the SceneLoader to be freed.
What happened instead?
The (huge amount) of memory allocated isn't freed. This can lead to gigabytes of memory lost after a few minutes, which makes the SceneLoader component unusable.
Attached project
The attached simple project loads and unloads a Scene3D that have a SceneLoader every 5 seconds, so you can see the the memory consumption growing indefinitely.
According to the Valgrind dump it seems that it's the memory allocated by the Assimp plugin that is not freed.
