From cf2a85efdade117e2169d6e26641016cbbf03ef0 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 29 Sep 2021 15:02:18 -0700 Subject: leaking_addresses: Always print a trailing newline For files that lack trailing newlines and match a leaking address (e.g. wchan[1]), the leaking_addresses.pl report would run together with the next line, making things look corrupted. Unconditionally remove the newline on input, and write it back out on output.
