I seem to have fixed the problem by setting the data variance on my osgText object to DYNAMIC. I'm wondering if this is the proper way to handle this situation though - because when I look at the StatsHandler for an example it appears to be modifying it's osgText nodes, but it does not set the data variance to DYNAMIC. Why does it work for the StatsHandler, but not for my code? Is it because the StatsHandler modifies its text during the event traversal and I modify my text during the update traversal? Should I be modifying it during event traversal only?
Thanks.

I seem to be having a problem where if I update some text in an update callback function it causes a segfault when I'm running the viewer in multi-threaded mode, but not in single threaded mode. I'm guessing because the text object is modified while is it being used by the render thread. Is there something wrong with how I am doing it? Thanks. Alex
