thread 'main' panicked at 'begin <= end (6 <= 0) when slicing ``

[killercup]

After a bunch of times pressing r while running rustfix on trust-dns:

Suggestion accepted. I'll remember that and apply it later.

I can't reproduce (tried the exact commit referenced and latest master). Probably fixed in clippy or rustc

[oli-obk]

Or... rustfix run in silent mode doesn't complain if the crate doesn't compile -.-

[oli-obk]

So the old version doesn't compile anymore. The openssl crate just doesn't work, even after a cargo update. Latest master doesn't crash rustfix, no matter which sub-crate of the repo I build.

Hm, I remember this is something I encountered a few times, but never could tell why. Are you running rustfix with debug assertions? Else the bound checks might be stripped away.

Heh, that's probably not that helpful. Open an issue?
