It is from = sem_open(). I don't get that before I upgraded the RELENG_6. http://people.freebsd.org/~mezz/test-sem_open.cc (took from configure's = = conftest) =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D % c++ -o test-sem_open -O2 -fno-strict-aliasing -pipe -g -pthread -pipe = = test-sem_open.cc % ./test-sem_open [1] 5761 invalid system call (core dumped) ./test-sem_open % grep sem_open /var/log/messages Oct 22 19:44:35 mezz kernel: pid 5761 (test-sem_open), uid 1001: exited = on = signal 12 (core dumped) Oct 22 20:00:45 mezz kernel: pid 6140 (test-sem_open), uid 1001: exited = on = signal 12 (core dumped) =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D I have decided to login in a jail that has RELENG_6 from July in the sam= e = local machine that have most debug enable. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D $ gdb test-sem_open test-sem_open.core Core was generated by `test-sem_open'.
