Hi, While using diffutils 3.11 instead of 3.10, i've noticed a critical bug in diff reproducible with the following setup: $ cd /tmp $ mkdir a b $ touch a/test $ echo content > b/test With diffutils 3.10, "diff -Naur a b" returns: diff -Naur a/test b/test --- a/test 2025-02-20 14:50:07.870258052 +0000 +++ b/test 2025-02-20 14:50:18.957287641 +0000 @@ -0,0 +1 @@ +content but with diffutils 3.11, the same command returns: File a/test is a regular empty file while file b/test is a regular file Given no mention of this change appear in the changelog, i'm guessing this is an unintended change. In my opinion this bug is critical and the 3.11 release should be marked as broken to avoid more distributions using it. Warm regards, Kate Deplaix
