Test PASSED
In the section of the POSIX spec that describes the SA_NOCLDSTOP flag in the sigaction() interface it is specified that if the SA_NOCLDSTOP flag is not set in sa_flags, then a SIGCHLD and a SIGCHLD signal **MAY** be generated for the calling process whenever any of its stopped child processes are continued. Because of that, this test will PASS either way, but note that the signals implementation you are currently run this test on chooses NOT TO send a SIGCHLD signal whenever any of its stopped child processes are continued. Again, this is not a bug because of the existence of the word *MAY* in the spec.
