Hi, Bone Baboon skribis: > `uname -srvmpio` outputs: > "Linux 5.9.3-gnu #1 SMP 1 x86_64 unknown unknown GNU/Linux" [...] > FAIL: execve-v.test > FAIL: execve.test Since the “dumping logs” phase failed, could you try to access the build logs under /tmp/guix-build-strace*? (You need to build with ‘--keep-failed’; see .) FWIW, I tried this: guix time-machine --commit=1f5543e7ff5db3f085edb5d6aa150be29bb4af43 -- \ build strace --no-grafts --check -K That gives me no less than 22 failures, though not the same ones, on “Linux 5.11.16-gnu #1 SMP 1 x86_64 unknown unknown GNU/Linux”. Attached is the ‘test-suite.log’ file. Weird that I get so many failures on a config that’s quite similar to that of the build nodes at ci.guix. That said, the strace test suite has always been very sensitive. Thanks, Ludo’.
