Hi Chuck,
Thanks for the stack traces, these do help give a better picture of
the deadlock, still not clear though, I'll need to study the set up of
the threading and the flow control to see if I can spot a failure
mechanism.
The osgviewer and osgcamera tests tell be that its the start up of
CullThreadPerCameraDrawThreadPerContext in both instances, so fix the
problem for one and its very very likely to fix it in the other.
As to what the problem might be... well I don't know. Thankfully this
thread model won't be the default selected thread model as it'll only
be selected for real high end machines that the cores to support it,
its a threading model that is real hungry for cores :)
Robert.
