Hi Butler;
It is well known problem :) I think your OSG system only compiled in release
mode and you are trying to build this example in debug mode, so program
throw bad_alloc exception. Try to build your example same build type as your
OSG system. If it is released mode you build your example in released mode
or vice versa.
Regards.
