Description

I'm using the latest today OF(master)+vs2012+win7

For example:

ofPlanePrimitive plane;

void ofApp::setup(){
    plane.setPosition(256,256,0);
    plane.setWidth(100);
    plane.setHeight(100);
    plane.setResolution(10,10);
    plane.mapTexCoords(0,0,1,1);
}

void ofApp::keyReleased(int key){
    cout<<"mesh save start"<<endl;
    plane.getMesh().save("test.mesh");  ///====>>>bug!
    cout<<"mesh save end"<<endl;
}

Research direction

Start by reproducing the crash with the provided ofPlanePrimitive example, then inspect ofMesh::save and the ofMesh::getIndex call shown in the stack trace. Determine why saving this mesh reaches an invalid index, and verify that saving the mesh completes without a crash.
