Bug ID: 22431
Summary: ld (binutils-2.29) segfaults when building Linux
kernel (v4.14) on Fedora 26 ppc64le
Product: binutils
Version: 2.29
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: mopsfelder at gmail dot com
Target Milestone: ---
Steps to reproduce:
- Make sure cross toolchain is installed:
sudo dnf install gcc-powerpc64-linux-gnu binutils-powerpc64-linux-gnu
- Clone Linux kernel mainline tree and build it with a specific .config:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
curl http://kisskb.ellerman.id.au/kisskb/buildresult/13052890/config/ -o
.config
yes "" | make CROSS_COMPILE=powerpc64-linux-gnu- oldconfig
make -j$(nproc) ARCH=powerpc CROSS_COMPILE=powerpc64-linux-gnu- V=1
Actual results:
ld segfaults during kernel build:
+ powerpc64-linux-gnu-ld -EB -m elf64ppc -pie --orphan-handling=warn --build-id
-X -o .tmp_vmlinux1 -T ./arch/powerpc/kernel/vmlinux.lds --whole-archive

I tested with the default binutils from Fedora 26:
binutils-2.27-28.fc26.ppc64le
I also tested with binutils-2.29 from Fedora rawhide (built for Fedora 26):
https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/source/tree/Packages/c/cross-binutils-2.29.1-1.fc28.src.rpm
$ rpm -qa | grep binutils | sort
binutils-2.27-28.fc26.ppc64le
binutils-powerpc64-linux-gnu-2.29.1-1.fc26.ppc64le
cross-binutils-common-2.29.1-1.fc26.noarch
