I think the problem is that TextureMapperPlatformLayerProxyGL is destroyed, but invalidate hasn't been called and m_targetLayer is still a non-null pointer to a released layer.
(In reply to Carlos Garcia Campos from comment #2) > I think the problem is that TextureMapperPlatformLayerProxyGL is destroyed, > but invalidate hasn't been called and m_targetLayer is still a non-null > pointer to a released layer. The Apple security says that this bug does not affect their platforms. Should someone looks after it?

Yes, that seems to be the problem. But in a normal scenario the destruction of the TextureMapperLayer pointed by m_targetLayer happens after invalidate has been called on the proxy. It should not be possible that the TextureMapperLayer is released but invalidate hasn't been called. There must be some tricky race condition here. Chijin, do you know if it's possible to reproduce the issue just by letting the attached example run? or do I need to do anything else, like closing the view or something?

Just run this html file and wait for 3~4 second and the it will trigger this crash. ./libexec/webkit2gtk-4.0/MiniBrowser /path/to/bufferoverflow_setContentsLayer.html
What seems to be happening here is an scenario that I didn't know was possible. The test creates and destroys several WebGLRenderingContext instances. Each instance is attached to a CoordinatedGraphicsLayer as their PlatformLayer, and propagated to the compositor thread, where the proxy for the PlatformLayer is activated and used by the corresponding TextureMapperLayer. This works fine. In theory, when the WebGLRenderingContext is destroyed, the attached CoordinatedGraphicsLayer is destroyed as well, which causes the compositor (inside the CoordinatedGraphicsScene) to call invalidate on the PlatformLayer proxy when deleting the layer. But what the test is doing is somehow detaching the PlatformLayer from the CoordinatedGraphicsLayer, but keeping the GraphicsLayer alive. On the compositor side, this causes that the proxy is not invalidated cause the layer doesn't have to be deleted. But when adopting the new scene state, we override the previous PlatformLayer (which becomes null), losing the reference to the previous proxy and the opportunity to call invalidate on it. After this scenario, if the TextureMaperLayer that was associated to the proxy is deleted before the proxy, when the proxy gets destroyed we get the use after free issue. I've checked that this is reproducible on ToT as well.

Hi, did you mean that this issue affect Safari as well?
> Hi, did you mean that this issue affect Safari as well? Nope. It affects the master branch, but only the WPE and GTK ports, as it happens in code that's specific to them.

I thought about it. But even when it would make the code simpler, the new var wouldn't make sense semantically inside the layersByBacking struct, as they are used for different things. Maybe it's because of the name "layersByBacking", which suggests a purpose that's not related to the new var. I don't know, it's just a completely subjective and philosophical decision with no strong arguments. I can move the new var in the struct if you think it's better ;)
