Public bug reported: While doing regression-testing for glibc 2.43 built on Ubuntu 26.04, it appears the code generated for static-pie binaries crashes on the call to _ld_relocate_static_pie(). This makes static-pie unusable on riscv. dynamic -fPIE do not seem to be affected. It is unclear to me whether the Ubuntu delta, or toolchain defaults, or compiler versions are to blame here.
I'm keeping a nostrip build of glibc for riscv to reproduce and trace the issue. https://launchpad.net/~simpoir/+archive/ubuntu/glibcriscv Reproduction: # set VM wget https://cloud-images.ubuntu.com/resolute/current/resolute-server-cloudimg-riscv64.img qemu-system-riscv64 -netdev user,id=n0,hostfwd=tcp::2222-:22 -device virtio-net,netdev=n0 -m 15G -smp 8 -drive file=resolute-server-cloudimg-riscv64.img -cdrom ~/seed.iso -machine virt -kernel /usr/lib/u-boot/qemu-riscv64_smode/u-boot.bin -cpu max -nographic -snapshot ssh -p 2222 localhost apt install gcc add-apt-repository ppa:simpoir/glibcriscv apt upgrade # libc-bin postinst will crash due to ldconfig being compile with static-pie. # From there we can get a simpler reproducer built against that version of glibc. echo 'void main() {}' >foo.c && gcc -static-pie foo.c && ./a.out ** Affects: glibc (Ubuntu) Importance: Undecided Status: Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2142067 Title: static-pie binaries crash on riscv64 with glibc 2.43 on resolute.
