Have the same behavior with OSG 1.0 Universal, and I submitted a bug-
report to apple: Bug ID# 4643964
Strange thing is, I remember having OSG 1.0 work a couple of months
ago, around April
I'll try to build the latest CVS with Xcode & see how far I get.
On the Linux front, OSG 1.1 works on CentOs4 (RedHat Enterprise 4) &
the binaries run on FedoraCore5 x86_64 (using 32-bit libraries).
I'm now looking into how a 64bit build on FedoraCore5 x86_64 behaves.

I have this same type of freeze with the 1.0 release when I run
osgviewer in full screen with one of our models. This is on a
MacBook Pro with 10.4.5/6/7. I also get the freeze on an intel iMac
and other MacBook Pros. I have another app that uses OpenGL through
the VTK framework and it also hangs.
I posted to the OpenGL list at Apple and some ATI engineers
responded that it is probably a driver issue on their part. You can
look through the archives at Apples mail list site. I think I
posted back in June.
They supposedly have a new driver that fixes my problem but it
did not make it into the 10.4.7 update. Hopefully it will make it
into the 10.4.8 update when that occurs. This bug has pretty much
stopped my 3D development on the Mac side until it gets fixed.
Although ATI _thinks_ they have it fixed, if you have a
reproducible bug that would be easy for ATI to compile, then post
to the opengl list out at Apple, ATI will hopefully reply and then
you can talk to them directly.
I also encourage you to file a bug with Apple's bug reporting
system. radar.apple.com (https://bugreport.apple.com/cgi-bin/
WebObjects/RadarWeb.woa) so that it gets logged in Apple's system.

When running the OSX binaries on a MacBook Pro, I am getting hard
freezing after a couple of seconds on some examples (osganimate).
On others (osgdepthshadow) it froze after pressing 'h' , it didn't
freeze when I moved from full-screen to window mode.
The freezes are nasty, I have to reboot the machine (ssh-in in from
anther machine & killing the process does not work)
I don't have an Intel Mac so I can't verify. It doesn't happen on any
of my PPC machines. I ran a CVS version a few months back on an Intel
iMac for about a week and did not experience any of your described
problems though. (There does seem to be a threading bug in somewhere
in OSG/Producer though which causes crashes on exit sometimes.)
So here are a few things to try:
- Do the old OSG 1.0 (Universal) binaries produce this same exact
problem on your machine (still available from the main download
page)?
If so, I would suspect a very bad Apple driver bug. If you could
compare against a different Intel Mac, it might be interesting.
- If the 1.0 does work, you might try compiling debug versions of
everything in 1.1. I changed the compiler optimization flag from -O3
to -Os in the 1.1 release. Maybe something screwy in compiler
optimizations is causing this.
- I heard something about an OpenGL driver snafu by Apple in the last
system update on the first day (10.4.7). I don't know the details,
but
maybe you need to look into this.
If this turns out to be an Apple problem, I strongly encourage you to
submit a bug report so they will fix it. They tend to take freezing
OpenGL bugs pretty seriously.
ps. having similar problems on a Fedora Core 5 x86_64, with OSG
built
for 32-bit (ARCHFLAGS = -m32), totally kills X, I'll do more testing
on this ne in 64-bit mode & on a CentOS4
Sorry, I don't know anything 64-bit Linux.
