I've wrote a program in win32 that does some drawing. After running it 
for a while it stops drawing the colors for the shapes I draw using GDI 
functions and it throws multiple time this error:
err:local:LOCAL_GetBlock not enough space in GDI heap 10bf for 36 bytes

The WM_PAINT message looks like this:
    GetClientRect (m_pMainWnd->m_hWnd, &rc);
    hdc = BeginPaint (m_pMainWnd->m_hWnd, &ps);
    // Create an off-screen DC for double-buffering
    hdcMem = CreateCompatibleDC (hdc);
    hbmMem = CreateCompatibleBitmap (hdc, rc.right, rc.bottom);
    hOld   = SelectObject (hdcMem, hbmMem);
    // Draw into hdcMem
    FillRect (hdcMem,&rc,CreateSolidBrush (RGB(255,255,255)) );
    m_pMainWnd->OnPaint (hdcMem);
    // Transfer the off-screen DC to the screen
    BitBlt (hdc, 0, 0, rc.right, rc.bottom, hdcMem, 0, 0, SRCCOPY);
    // Free-up the off-screen DC
    SelectObject (hdcMem, hOld);
    DeleteObject (hbmMem);
    DeleteDC     (hdcMem);
    EndPaint (m_hWnd, &ps);

OnPaint method for m_pMainWnd looks like this:
    HPEN hPen = CreatePen( PS_SOLID, 3, m_cCurPen); // m_cCurPen: COLORREF
    HBRUSH hBrush = CreateSolidBrush( m_cCurBrush ); // m_cCurBrush: 

    HPEN hOldPen = (HPEN) SelectObject( dc,hPen );
    HBRUSH hOldBrush = (HBRUSH) SelectObject( dc,hBrush );
    Ellipse (dc,m_ptOrg.x, m_ptOrg.y, m_ptOrg.x+m_ptDim.x, 

    SelectObject( dc,hOldPen );
    SelectObject( dc,hOldBrush );

    DeleteObject( hPen );
    DeleteObject( hBrush );

What did I do wrong?
