Bug#831449: lintian on Sid amd64 reports volatile false spelling errors in binaries
Subject: lintian on Sid amd64 reports volatile false spelling errors in binaries
Package: lintian
Version: 2.5.45
Severity: normal
Tags: upstream
Hi,
I encountered the problem with lintian checks while and after packaging
libisoburn 1.4.4-1.
After apt-get dist-upgrade on my Sid VM on juli 4 2016 and debuild from
libisoburn-1.4.4.tar.gz i got from lintian a warning about a typo "lengH"
in the resulting shared library file. This is a false positive.
So i overrode it.
But after upload by my sponsor i see on
https://lintian.debian.org/full/pkg-libburnia-devel@lists.alioth.debian.org.html#libisoburn
the complaint
unused-override
spelling-error-in-binary *libisoburn.so* lengH length
Reason for the "lengH" complaint on my Sid is probably the output of
strings which reflects a strange habit of gcc to chop texts into pieces
which are separated by non-printable bytes.
Source line:
xorriso/iso_manip.c: "Suitable are strings of length 4 or length 1");
yields with "strings" from libisoburn.so
SuitableL
th 1I
are strA
ings of E1
length 41
or lengH
Binary snippet from libisoburn.so:

A similar binary representation can be found in libisoburn.so when i
build it on my Debian 8 workstation. So this problem is not just about
newest gcc versions.
Another similar override in debian/libisoburn1.lintian-overrides is not
reported as unused by lintian.debian.org:
# Here: "ment off" from "Displacement offset leads outside 32 bit range"
libisoburn1 binary: spelling-error-in-binary *libisoburn.so* ment meant
So i assume that lintian.debian.org still spellchecks binaries and
still finds false positives in them.
Have a nice day :)
