It is enough to run the binary to see the segfault: pokybuild@debian12-vk-3:~/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/sysroots-components/x86_64/qemu-system-native/usr/bin$ ./qemu-img Segmentation fault Reproduction: wget http://sstate.yoctoproject.org/all/universal/78/ea/sstate%3Aqemu-system-native%3Ax86_64-linux%3A10.1.1%3Ar0%3Ax86_64%3A14%3A78eaa8f4520be87b4afccd3eedea070dbedc5453219e96f16102bea454a964c8_populate_sysroot.tar.zst zstd -d sstate\:qemu-system-native\:x86_64-linux\:10.1.1\:r0\:x86_64\:14\:78eaa8f4520be87b4afccd3eedea070dbedc5453219e96f16102bea454a964c8_populate_sysroot.tar.zst mv sstate\:qemu-system-native\:x86_64-linux\:10.1.1\:r0\:x86_64\:14\:78eaa8f4520be87b4afccd3eedea070dbedc5453219e96f16102bea454a964c8_populate_sysroot.tar sstate.tar tar -xf sstate.tar ./recipe-sysroot-native/usr/bin/qemu-img qemu-img: Not enough arguments Try './recipe-sysroot-native/usr/bin/qemu-img --help' for more information $ ~/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/sysroots-uninative/x86_64-linux/usr/bin/patchelf-uninative --set-interpreter /home/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/sysroots-uninative/x86_64-linux/lib/ld-linux-x86-64.so.2 ./recipe-sysroot-native/usr/bin/qemu-img pokybuild@debian12-vk-3:~/yocto-worker/reproducible/build/build-st/reproducibleB-extended/tmp/work/x86_64-linux/qemu-system-native/10.1.1/temp$ ./recipe-sysroot-native/usr/bin/qemu-img Segmentation fault I was also able to reproduce this locally using my own local build. So simply put: Download the qemu sstate Run patchelf-uninative from the uninative tarball on the binary to change the interpreter It will segfault Almost certainly due to a bug in patchelf. 102935 1 richard.purdie 2025-10-14 16:46:29 +0000 $ /media/build/poky/build/tmp/sysroots-uninative/x86_64-linux/usr/bin/patchelf-uninative --print-interpreter ./recipe-sysroot-native/usr/bin/qemu-img /srv/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleA/tmp/sysroots-uninative/x86_64-linux/lib/ld-linux-x86-64.so.2 so the binary in sstate was produced by a reproducible build 102944 2 richard.purdie 2025-10-15 17:00:26 +0000 Upgrading patchelf appears to fix it. We need to merge the fix, then build and issue a new uninative. 102960 3 randy.macleod 2025-10-16 14:50:55 +0000 We'll generate a new uninative for M4. 102984 4 mhalstead 2025-10-16 22:31:29 +0000 Uninative 5.0rc1 is built and ready for testing. A patch is on the openembedded-core@lists.openembedded.org. 103156 5 richard.purdie 2025-10-30 15:31:31 +0000 This was merged and the issue is now hopefully resolved: https://git.yoctoproject.org/poky/commit/?id=cb478c6228f0654ded5ac19a8a8d2f8ba9a717af
