Package: binutils-gold Severity: important Version: 2.22-8 Tags: upstream I have recently found that the gold linker incorrectly links a FUSE application to an old (/arbitary?) API level of a function.
In order to reproduce and demonstrate this issue, in a jessie cowbuilder environment the following steps can be followed: install git, pkg-config, libfuse-dev, vim-common, the in a directory such as /tmp clone the tup source tree into two distinct directories: root@heidi:/tmp# git clone http://github.com/eddyp/tup.git tup-bfd Cloning into 'tup-bfd'... remote: Counting objects: 18671, done. remote: Compressing objects: 100% (8339/8339), done. remote: Total 18671 (delta 10447), reused 17666 (delta 9494) Receiving objects: 100% (18671/18671), 9.91 MiB | 599 KiB/s, done. Resolving deltas: 100% (10447/10447), done. root@heidi:/tmp# git clone tup-bfd tup-gold Cloning into 'tup-gold'... done. (the failing commit is 81d0371 and is tagged 'binutils-gold-bug') Then try to build with bfd linker (the build will fail, if ran in a cowbuilder jessie chroot, it's OK). root@heidi:/tmp# cd tup-bfd/ root@heidi:/tmp/tup-bfd# ld --version GNU ld (GNU Binutils for Debian) 2.22 Copyright 2011 Free Software Foundation, Inc.
