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.

I have decided to login in a jail that has RELENG_6 from July in the
same
local machine that have most debug enable.

BTW: Please add me in CC, I am not on the list.
You need to make sure you have "options P1003_1B_SEMAPHORES" in your
kernel. These POSIX IPC constructs are labeled as being very
experimental, and this is not a default option.
I guess I am safe then as I can ignore these cores.. Thanks! Isn't kernel
supposed to be avoid the crash? I don't see any of crash before I upgraded
to last night of RELENG_6.
Cheers,
Mezz
Joe
