With trunk (for gcc 14) I correctly get a NPD warning (true positive): https://godbolt.org/z/a5h38cz7d With gcc 13.2, I don't (false negative): https://godbolt.org/z/PKnToYK8v I've been rewriting C string handling for gcc 14, so it's likely this now working is a side-effect of that. Keeping open to track adding a regression test for this.
