Surprisingly this happens while allocating an object into a block.

Either of LocalAllocator_tryAllocateSmall() or LocalAllocator_overflowAllocateSmall() is calling Line_update(block, object) while object isn't within the block's bounds :raised_eyebrow:

That should be impossible, of course. Unless the cursors went wrong in LocalAllocator for some reason?
