Do anyone has any problem with sem_open() crash?

[Jeremy Messenger]

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

===============================

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

BTW: Please add me in CC, I am not on the list.
