| |
From: Kees Cook <keescook@chromium.org>
[ Upstream commit cf2a85efdade117e2169d6e26641016cbbf03ef0 ]
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.
