Thanks a lot for looking into this! If you have installed a Debian unstable big-endian system, the easiest way = to get such a setup by creating an sbuild chroot. You should set up an sbuild chroot for both powerpc and ppc64: $ sbuild-createchroot --arch=3Dpowerpc $ sbuild-createchroot --arch=3Dppc64 and then build the glibc package using sbuild for both powerpc and ppc64 in parallel which is what makes the VM and the host crash during the testsuite: $ dget -u https://deb.debian.org/debian/pool/main/g/glibc/glibc_2.32-2.dsc In one shell: $ sbuild -d sid --arch=3Dppc64 --no-arch-all glibc_2.32-2.dsc and in a second one: $ sbuild -d sid --arch=3Dpowerpc --no-arch-all glibc_2.32-2.dsc If glibc doesn't trigger the crash, try gcc-10 or llvm-toolchain-13: $ dget -u https://deb.debian.org/debian/pool/main/l/llvm-toolchain-13/llvm-toolchain-= 13_13.0.0~+rc2-3.dsc $ dget -u https://deb.debian.org/debian/pool/main/g/gcc-11/gcc-11_11.2.0-5.= dsc --=20 You may reply to this email to add a comment.
