Debugging heap corruption in windbg (glEnableVertexAttribArray gives access violation)

void TE::Render::APIVertexBufferLayout::Enable()
{
    if (m_hasPosition)
    {
        glEnableVertexAttribArray(0);
        glVertexAttribPointer(0, m_positionValueCount, m_positionValueType, GL_F    ALSE, m_stride, (void*)m_positionOffset);
    }
    if (m_hasNormals)
    {
        glEnableVertexAttribArray(1);
        glVertexAttribPointer(1, m_normalValueCount, m_normalValueType, GL_FALSE, 0, (    void*)m_normalOffset);
    }
    for(unsigned i = 0; i < m_textureCount; ++i)
    {
        glEnableVertexAttribArray(2+i);
        glVertexAttribPointer(2+i, m_textureValueCount[i], m_textureValueType[i], GL_FALSE, m_stride, (void*)m_textureOffset[i]);
    }
}

I was getting a access violation on the call glEnableVertexAttribArray(0) and after talking to someone in the #opengl irc channel it seemed like my heap was corrupted.

So I enable full pagehead with application verifier and launched my application through the debuger (visual studio 2012):

When I launched the application visual studio shows me a break point on the line m_apiVertexBuffers[&mesh]->Enable() in the below function.. but that is actualy after where I got the breakpoint earlier.. m_apiVertexBufferLayouts[&mesh]->Enable() is the call to the function in the paste above so it breaks in there..

void TE::Render::Renderer::Enable( const Mesh& mesh )
{
    assert(m_apiVertexBufferLayouts.find(&mesh) != m_apiVertexBufferLayouts.end() && "VertexBufferLayout not loaded");
    assert(m_apiVertexBuffers.find(&mesh) != m_apiVertexBuffers.end() && "VertexBuffer not loaded");
    assert(m_apiIndexBuffers.find(&mesh) != m_apiIndexBuffers.end() && "IndexBuffer not loaded");

    m_apiVertexBufferLayouts[&mesh]->Enable();
    m_apiVertexBuffers[&mesh]->Enable();
    m_apiIndexBuffers[&mesh]->Enable();
}

How can I debug this further? This is my first time in a debugger so I'm abit confused..
