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

fuse_mount: No such file or directory
tup error: Unable to mount FUSE on .tup/mnt
The bfd linker will correctly link the elf to use the fuse_new@FUSE_2.6 version:
root@heidi:/tmp/tup-bfd# readelf -a build/tup | grep fuse_new
00000072e960 002b00000007 R_X86_64_JUMP_SLO 0000000000000000 fuse_new + 0

2984: 0000000000000000 0 FUNC GLOBAL DEFAULT UND fuse_new@@FUSE_2.6
But with the gold linker:
root@heidi:/tmp/tup-bfd# cd ../tup-gold/
root@heidi:/tmp/tup-gold# aptitude install binutils-gold
root@heidi:/tmp/tup-gold# ld --version
