I'm just finishing the bisection and think I have the commit that caused
this but I'm now just testing commits +-1 from that commit to make sure
and if it is will try reverting just that commit against HEAD as well.
Using the sigaltstack coroutine backend did not make any difference. I
actually am using that now and then reverted it when initially testing
1.3 to make sure that was not the source of the regression with no
change in behaviour at all. Also yes I would be using rthreads. All
development happens against -current.

So what is causing this is this commit...
c166cb72f1676855816340666c3b618beef4b976
semaphore: implement fallback counting semaphores with mutex+condvar
OpenBSD and Darwin do not have sem_timedwait. Implement a fallback for
them.
If I remove that, since OpenBSD 5.2/-current has sem_timedwait, then it
works just fine.

Paolo,
As you wrote the fallback code which is used when sem_timedwait() is
missing could you please take a look at this when you have some time? I
can test any patches you might come up with.

Can you try this:

I was experiencing this bug fairly regularly with QEMU 1.3.0 on OS X
10.8. All my emulations of debian environments couldn't even get past
installation, because this bug would hit too early.
Brad, it looks like 2 weeks ago you got a patch authored that fixes this
fallback code. That's commit a795ef8dcb8cbadffc996c41ff38927a97645234,
which was originally from Paolo.
I have applied this patch locally to a copy of QEMU 1.3.0 and my
problems went away. Thus I think this bug is fixed in HEAD, but I do not
know if the commit has been put in another branch.

I am currently experiencing this on Mac OS X 10.8 also, custom built
yesterday evening from the master branch.
I have looked at the diff and it looks like it has been applied in qemu-
thread-posix.c file, but no luck.
Any pointers? Thanks

I had the same problem on Mac OS X 10.8.2 with qemu 1.3.0, but it is now
fixed in the current master branch. I can confirm that the commit
a795ef8dcb8cbadffc996c41ff38927a97645234 fixes this problem. This commit
can also be applied to the 1.3.0 source.

Before the patch in question was commited running QEMU 1.3.0 hosted on
OpenBSD I was able to cause QEMU to crash reproducibly by just booting
OpenBSD within QEMU and upon the kernel accessing the virtual disk to
read the disklabel or during an install writing the disklabel. After the
patch was applied I was not able to cause any crashes and went through a
handful of installs without any issues.
Are you able to build QEMU with debug symbols and get a backtrace once
it has crashed on your OS X system?

The other question I have is if you look at the commit I mentioned as
causing the crash (at least on OpenBSD) and revert that change from
either 1.3.0 or HEAD branch and build QEMU on OS X does the crashing
you're experiencing go away?

On line 216 of qemu-thread-posix.c I have commented out the
++sem->count; which seems to be the only change made in that commit.
Unfortunately it still crashes with that error.
I have compiled with --enable-debug but not sure how to get a backtrace
or even a log of what goes wrong.

Aaron, this added line in qemu-thread-posix.c is the fix, qemu is
expected to crash once this is removed.
I guess Brad meant to revert c166cb72f1676855816340666c3b618beef4b976
which introduced the fallback code. However, reverting this commit alone
will not work on Mac OS X as sem_timedwait() is not available (and the
reason why the fallback code was added at all).

I was unable to reproduce the original issue on Mac OS X 10.8.4 using
the current master. However, I was also unable to reproduce the original
issue on the stable-1.5 branch which does not have the fix by Izumi
Tsutsui linked above. As this second fix is only for a problem that
appears in certain load situations, of course I might not be able to
reproduce it.
I also reviewed the code on master I am confident that the solution is
correct now.
