I've tried to reproduce this on a very similar system I have: linux-3.18.5 kernel-headers-3.18.5 glibc-2.17 gcc-4.9.2 It passes the test there. > i've verified it's not a load issue (as my things normally build+test in > parallel) -- when i run `make check TESTS=detach-stopped.test` when things > are > quiet, it still fails. > > i manually added set -x to the top of the file -- that log is attached. > should > init.sh run `set -x` mode all the time to make the failing logs a bit more > helpful in edge cases like this ? It would certainly help in case of potentially hanging tests like detach-sleeping.test or detach-stopped.test. I'm not sure about all tests, but let's try it. > detach-stopped.test.tmp contains just this: > Process 1267 attached > restart_syscall(<... resuming interrupted call ...> That is, either "kill -STOP" failed to stop "sleep" or PTRACE_EVENT_STOP hasn't been delivered to strace.
