--- Comment #27 from Christoph Bartoschek  ---
HeidSQL calls the function

BOOL dibdrv_RoundRect( PHYSDEV dev, INT left, INT top, INT right, INT bottom,
                       INT ellipse_width, INT ellipse_height )

with ellipse_width == 0 and ellipse_height == 0, resulting in max_points == 0.
Then in get_arc_poitns the empty top_points array is written to.

I guess, either the function has to return early in such a case or one needs to
check why the ellipse_width and ellipse_height are both 0 and fix the calling
location.
