Re: [Sbcl-help] a question about retained instances and map-referencing-objects

[73budden . <bud...@gm...>]

Hi! I'm not an expert in SBCL, but I know that SBCL's garbage
collector on some platforms is partially conservative. So any objects
can be referenced from some non-pointer objects on the stack and no
object is guaranteed to be removed from the memory.

It is described somewhere in the documentation, but I don't remember
where. And this was said in the discussions you refer to.

If I was on your place, I'd try to reorganize application so that
unnecessary foreign objects are deallocated explicitly. Alternative is
just to make your foreign environment tolerate this kind of leak.
After all, in garbage collection there is no guarantee that your
object is collected at any particular moment of time so there is no
reason to rely upon it.
