QOpenGl - VAO - crash crash crash!

[Dariusz]

I'm out of ideas... wrrr!!!

Ok so

/// make by init VAO

initializeGL(){
    makeCurrent();
    initializeOpenGLFunctions();
    mFunctions = new QOpenGLFunctions_4_5_Core();
    mFunctions->initializeOpenGLFunctions();

    getShader()->bind();
    mVao = new QOpenGLVertexArrayObject();
    mVao->create();
    mVao->bind();

    mVertexBuffer = new QOpenGLBuffer(QOpenGLBuffer::VertexBuffer);
    mVertexBuffer->create();
    mVertexBuffer->setUsagePattern(QOpenGLBuffer::StaticDraw);
    mVertexBuffer->bind();

   getShader()->enableAttributeArray("position");
   getShader()->setAttributeBuffer("position", GL_FLOAT, 0, 3, sizeof(QVector3D));

    mNormalsBuffer = new QOpenGLBuffer(QOpenGLBuffer::VertexBuffer);
    mNormalsBuffer->create();
    mNormalsBuffer->setUsagePattern(QOpenGLBuffer::StaticDraw);
    mNormalsBuffer->bind();

    mIndicesBuffer = new QOpenGLBuffer(QOpenGLBuffer::IndexBuffer);
    mIndicesBuffer->create();
    mIndicesBuffer->setUsagePattern(QOpenGLBuffer::StaticDraw);
    mIndicesBuffer->bind();

    mVertexBuffer->release();
    mNormalsBuffer->release();
    mIndicesBuffer->release();
    mVao->release();
}

add data to vao at latter data...

void addData(vector<data>data){
makeCurrent();
....
... process data in to 3 vectors 

    mVao->bind();

    mVertexBuffer->bind();
    mVertexBuffer->allocate(mVertex.get(), verteSize * sizeof(VRay::Vector));
    
    getShader()->enableAttributeArray("position");
    getShader()->setAttributeBuffer("position", GL_FLOAT, 0, 3, sizeof(VRay::Vector));

    mNormalsBuffer->bind();
    mNormalsBuffer->allocate(mNormals.get(), normalsSize * sizeof(VRay::Vector));

    mIndicesBuffer->bind();
    mIndicesBuffer->allocate(mIndices.get(), indicesSize * sizeof(int));
    
    mVertexBuffer->release();
    mNormalsBuffer->release();
    mIndicesBuffer->release();
    mVao->release();
    doneCurrent();
}

And paint :

paintGl(){
getShader()->bind();
vao->bind();

glDrawElementsBaseVertex()
vao->release();
getShader()->release();
}

And I just get a crash every time... If I bind QOpenGLBuffer in paint GL after vao->bind(), everything runs, but then I'm not using VAO but buffers... what on earth am I doing wrong here?! QT!!!!!!
