#1763 LV2: Calf Memory Leaks

[Ted Felix]

As I've been playing with the Calf plugins, I've noticed massive new memory leaks. Sometimes over 2MB worth when I flip through the Calf plugins and display their editors.

I suspect a good portion of the issue is related to AudioPluginLV2GUIWindow.cpp:222. It's a call to LV2UI_Descriptor::instantiate(). Within LV2UI_Descriptor there is a cleanup() routine which looks like it might need to be called once we are done with the handle provided by instantiate(). Many of the leaks appear connected to this instantiate() call. I do not see a LV2UI_Descriptor::cleanup() call anywhere. Hopefully this will solve a significant number of the memory leaks.

Yes I saw memory leaks from calf plugins. I blamed the plugin for not cleaning up properly (the lazy thing to do!) but maybe a good idea to look more closely.
There is a call to cleanup in the AudioPluginLV2GUI destructor - I believe it es getting called when the window is closed.
I can check a bit further.

Ok. I didn't find the cleanup() call immediately, so I assumed it might be on our side. I won't be surprised if it isn't us. Just so long as we are keeping an eye on this. It's really making it difficult for me to find legitimate memory leaks now.
