Hi Robert,
With latest SVN. See the attached testcase (reduced from the raytracing
example posted earlier).
With the default threading model I get crashes on exit for e.g.
dumptruck, cow and cessnafire:

With OSG_THREADING set to SingleThreaded it crashes on exit when viewing
cessnafire.osg (and other models containing particle systems). I don't
get such crashes on e.g. dumptruck and the cow anymore.
[cessnafire.osg, same as above]
