Follow-up Comment #24, bug #64421 (project groff): Hello!
With the help from the package maintainer Tobias Powalowski, I was able to reproduce the broken build locally. When I build with the `makepkg` tool, the resulting binary *does not* have the bug. When I build with the "reproducible build" approach as explained in https://wiki.archlinux.org/title/DeveloperWiki:Building_in_a_clean_chroot#Convenience_way, then the resulting binary *does* have the bug. To build a binary which has the bug, do: * Check out the Arch Linux package as explained on previous comment and cd to the directory with the PKGBUILD file. * Run "extra-x86_64-build" to build it in a fresh chroot I attached the package with and without the bug in the file good-and-bad-groff.tar below. The subfolders "good" and "buggy" contain the binary package in the working and buggy versions. These package files can be extracted with GNU tar using: tar --zstd -x -f groff-1.23.0-3-x86_64.pkg.tar.zst I also included the log files from the two builds. The compiler options are logged there as part of the ./configure run. The flags differ, but not much: The working package used: C compiler and options : gcc -march=x86-64 -mtune=generic -O2 -pipe -fno-plt -fexceptions -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security -fstack-clash-protection -fcf-protection The buggy package used: C compiler and options : gcc -march=x86-64 -mtune=generic -O2 -pipe -fno-plt -fexceptions -Wp, -D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security -fstack-clash-protection -fcf-protection -g -ffile-prefix-map=/build/groff/src=/usr/src/debug/groff -flto=auto Surprisingly it is the build which had the bug which has an additional -g flag. (But it's possible that the debug symbols were stripped after the build step, to produce separate packages for the binaries and debug symbols) Another thing that looks suspicious is -flto=auto. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?64421> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
