Application-A320 crashed in ASSERT_PREDICATE

[Mud-Player]

My dev envirment : MSVC2017_x64 osg3.6.3 boost_1.7.0
First, I run without any source change, debug error happend at "Library-Graphics/Light.cpp line 203“ with ASSERT_PREDICATE failed;
Then, I changed the file a320.ive.xml to limit fInnerAngleDegrees/fOuterAngleDegrees in 0-180, but this time error happend in osg::ref_ptr<osg::StateSet const>::get, and debug window shows "this" value is 0xfeeefeeefeeeff0e.
thanks a lot for help!
