Help with runtime error at MapNode::get()

[AhmedAredah]

I am trying to read an earth file and visualize it. The file reading went good however, when I pass it to MapNode::get() it throws an error. Below is the portion of the code that loads the file:

   // read in the Earth file:
   osg::ref_ptr<osg::Node> node  = osgDB::readRefNodeFile(filename);
   if (!node .valid())
   {
       qDebug() << "Failed to load Earth model from: " <<
           QString::fromStdString(filename);
       return;
   }
   
   osg::Node* n = node.get();
   osg::ref_ptr<MapNode> mapNode = MapNode::get(n);          << error in insertion here. 
   if (!mapNode.valid())
   {
       qDebug() << "Loaded scene graph does not contain a MapNode";
       return;
   }

Error: The inferior stopped because it triggered an exception.

Debug Assertion Failed!

Expression: vector emplace iterator outside range
For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts.

The error happens at this line (subprocess of the MapNode::get() function):
inline void pushOntoNodePath(Node* node) { if (_traversalMode!=TRAVERSE_PARENTS) _nodePath.push_back(node); else _nodePath.insert(_nodePath.begin(),node); }

The node is being inserted at the beginning of the vector but I have no clue why it is throwing that error. everything seems fine to me.

Note: I am loading one of the test earth files (glsl.earth)

Env: Windows 11 x64 bit.

This error is occuring inside OpenSceneGraph. I suspect you have a bad build. Maybe you are mixing versions in your path? Or mixing debug and release builds?

Oh, that makes sense. Thank you for helping out and for your patience. I do appreciate it.

I was passing ${osgEarth_LIBRARIES} in the cmake file and didn't pay attention to the referred file.
