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-de...@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: 00094e50 : 61 62 6c 65 4c 8d 05 71 5b 01 00 41 c7 84 24 bc a b l e L q [ A $ 00094e60 : b1 02 00 74 68 20 31 49 89 84 24 94 b1 02 00 48 t h 1 I $ H 00094e70 : b8 20 61 72 65 20 73 74 72 41 c6 84 24 c0 b1 02 a r e s t r A $ 00094e80 : 00 00 49 89 84 24 9c b1 02 00 48 b8 69 6e 67 73 I $ H i n g s 00094e90 : 20 6f 66 20 45 31 c9 49 89 84 24 a4 b1 02 00 48 o f E 1 I $ H 00094ea0 : b8 6c 65 6e 67 74 68 20 34 31 c9 49 89 84 24 ac l e n g t h 4 1 I $ 00094eb0 : b1 02 00 48 b8 20 6f 72 20 6c 65 6e 67 48 89 da H o r l e n g H 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.
