I agree that this is likely not an issue with AppKit or Core Animation. I’d
start by search your code for ‘saveDocumentAs:’. Whatever object that is
supposed to be getting called on is likely the object that is being smashed.
You could also try running with the Static Analyzer & Address Sanit

I think, in the scenario I described, zombie detection won’t help. It’s not an
undead object, but an undead reference.
It’s also worth noting, though no help at all to you at the mom

Unfortunately, it’s not obvious that it’s an
Anyone else seen this?
It’s happening very rarely but enough to be a concern. I can’t find any way to
