Hi, The misc/exec-bad-unicode test that was added on 2026-10-04 fails in an environment with clang + UBSAN + ASAN.
FAIL: tests/misc/exec-bad-unicode ================================= + read executor + LC_ALL=C + stdbuf -oL $'./\377|\355\272\255|\\u0089|\355\246\277\355\277\277' $'\377|\355\272\255|\\u0089|\355\246\277\355\277\277' + test 127 = 0 + case "$executor" in + false + cat err /bin/bash: symbol lookup error: /home/runner/work/ci-check/ci-check/coreutils-2026-10-13/build/src/libstdbuf.so: undefined symbol: __asan_option_detect_stack_use_after_return + fail=1 This is obviously related to the 'stdbuf' program. But there are surely other stdbuf tests, that don't fail?? What do they do differently? Bruno
