There was a problem hiding this comment.
So that we don't regress on this in the future, could you add a link to this PR explaining the workaround?

Reproducible in "examples/ASCollectionView" by enabling
ASYNC_COLLECTION_LAYOUTand popping the view controller after just 2 seconds (this line). The crash occurs when a containing view controller is popped out right after its collection view finished a batch update, but before an update animation settles. As soon as the view controller is deallocated, its collection view's layout is invalidated. Then when the update animation stops, it asks for the layout's content size and triggers the assertion. Fix by returning a zero size instead.
