Using the default QOpenGLTexture example in initializeGL() crash the application (right after the QOpenGLTexture creation):
QOpenGLTexture *texture = new QOpenGLTexture(QImage(fileName).mirrored());
texture->setMinificationFilter(QOpenGLTexture::LinearMipMapLinear);
texture->setMagnificationFilter(QOpenGLTexture::Linear);

Happen with Qt 5.2.0 MSVC2012 x64 Angle.
Could not get QImage transferred to a QOpenGLTexture with setData either, same crash occur.
