Error -1073741819 o (C0000005)

Hi,

I'm trying to add "Vertex" elements to a vector. However, when I try to execute the program, I have an error: Error -1073741819 (or C0000005)

What does this error mean? Can you help me to resolve it? Thanks!

Here's the code

The function described before in xml.h:
 
 
void ProcessFile(std::vector<Joint> *joints, TiXmlDocument* pParent);

Do you know how to use a debugger? It would be good to set a breakpoint and step through with a debugger to pinpoint the line causing the problem.

v.x = atof(word);
word = strtok(NULL," ");
v.y = atof(word);
word = strtok(NULL," ");
v.z = atof(word);
word = strtok(NULL," ");


You're trying to tokenize NULL.

EDIT: Ahh, nevermind.

I don't know how to use the debugger (I'm using Qt SDK -> QtCreator). However I know where's the problem, is in this function, where I do the push_back:
1
2
3
4
 
void Joint::addVertex(Vertex &v)
{
    vertexVector.push_back(v);
}


I use some qDebug() to know where the program stop (qDebug() << is like "cout <<").
