Well, sorry I forgot to mention it certainly works with singlethreaded
mode. I could try to reproduce it with a simpler example but I think
osgviewer is as lean as it gets. If I don't switch on the HUD in
osgviewer the problem does not occur - or lets say I can't reproduce it.
We have some other applications which could benefit from multi threading
but show exactly the same behaviour when using a HUD i.e osgText.

Hi Hartmut,
The FreeType plugin usage is guarded to prevent thread problems so
while FreeType isn't thread safe, this shouldn't affect OSG-2.6, and
almost certainly has no barring on the crash you describe.
The crash you looks to be CGL issue, whether this is a threading issue
or otherwise I cannot say at this stage. Try chnaging the threading
models in osgviewer by pressing 'm', or run the app with the command
line option --SingleThreaded etc.
Robert.

I seen some other threads mentioning FreeType not being thread save. This is
OSG 2.6 branch
This is replicable with plain osgviewer on OSX on a MBP 2.4
To replicate:
export OSG_WINDOW='20 20 800 600'
open osgviewer cow.osg
press 's' to show the stats
with '<' and '>' go up and down the window resolutions ...
it crashes always at the same point ... see below
Is there any solution? If so will it be backported to 2.6?
Cheers,
Hartmut
