I have just added some more checks into src/osgText/Text.cpp so that it
should mange the chached coordinate arrays more robustly, your example no
longer crashes like it was prior these latest changes.  This fixes are now
checked into svn/trunk and the OSG-3.4 branch and part of the

While your example doesn't crash for me now, it hangs in the swap buffers,
without even a window appearing on screen so it looks like there are other
problems with this particular example unrelated to the osgText issue that
is hopefully now resolved.  I'm no Qt expert so am not about to dive into
why your example doesn't bring up a context correctly.

Could you please try out OSG svn/trunk, OSG-3.4 branch or the 3.4.0-rc10
and let me know if your text usage now works with your application.
