V6062. Possible infinite recursion.

Dec 04 2018

The analyzer has detected a possible case of infinite recursion. It is very likely to result in a stack overflow and throwing a 'StackOverflow' exception.

Let's consider the example from the real project which resulted in such a situation:

@Override
public void glGenTextures(IntBuffer textures) {
    gl.glGenTextures(textures);
    checkError();
}

@Override
public void glGenQueries(int num, IntBuffer ids) {
    glGenQueries(num, ids); // <=
    checkError();
}

A developer made a typo and called the wrong method, which became the reason of infinite recursion occurrence. The method 'glGenQueries' had to be called from the 'gl' object in the way it is usually done in other functions.

Fixed example:

@Override
public void glGenTextures(IntBuffer textures) {
    gl.glGenTextures(textures);
    checkError();
}

@Override
public void glGenQueries(int num, IntBuffer ids) {
    gl.glGenQueries(num, ids);
    checkError();
}

This diagnostic is classified as:

You can look at examples of errors detected by the V6062 diagnostic.
