Comment 3 for bug 1052765

If you want to back-port the fix, here it is:

      CHECKGL(glVertexAttribPointer(shader_attribute_location,
        vtxelement.NumComponent,
        vtxelement.Type,
        GL_FALSE,
        vtxelement.stride_,
        (void*)&vtxelement.Offset));

Note the & added on the last line.
