Blender crashes when the user scales up an image into huge scales. This is due to integer overflow when doing memory allocations. So we fix this by using larger integers when doing math on memory allocations and indexing. Note that while this solves the random crashes, users scaling up images to huge scales will face things like the OOM killer activating or at best significant slow downs due to swapping. It is not clear how to handle such cases, but something like a global maximum size option that is set to 16k by default might be worth adding.
