Hello folks,
Last night, I have upgraded from July RELENG_6 to last night. I have
reinstalled all of ports and I noticed that the log/messages is collecting
a few of 'pid 14699 (conftest), uid 0: exited on signal 12 (core dumped)'.
I dig in the configure and found a location of crash. 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)
===============================
% 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)
===============================
I have decided to login in a jail that has RELENG_6 from July in the same
local machine that have most debug enable.

$ gdb test-sem_open test-sem_open.core
