Hi Stef,

> Apparently what Pablo was looking for before leaving on vacation was if forwarder logic or something related with the write barrier and the GC was not nilling one stack element. But I may have misunderstood.

That aligns with one thing I'm seeing, the Frame Pointer not being updated after an object is moved and it's old copy converted to a forwarder.

However there are other assertions being printed before the Frame Pointer corruption which I don't understand yet.

It would be great if Pablo could pass on what he knows after he gets back from leave.
