LLMs are surprisingly good at reducing crash samples. I've had success with "this project crashes my static analysis tool with the following command, try to shrink the repro whilst preserving the crash. Commit each smaller version to a branch".

Got a bug report on difftastic saying it crashes with an error: "should be impossible: expected XYZ". I am very glad I phrased my assertion as *should*!

I'm beginning to think this last sentence was a mistake. Lots of software fixes crashes in new versions. Perhaps I should have a "N releases since last fix for a crash" count?
