- Attempting to kill a buffer that isn't saved, with any choice, has a high chance of causing a segmentation fault. Yes and no answers almost certainly segfault. Save sometimes doesn't.
- A rare bug with searching / reverse searching. Can't remember how I triggered it. Also causes a segfault.
- cmdid_copy and cmdid_cut don't always add stuff to the clipboard. Sometimes, they work, mostly they don't. Not sure what causes it.
