HOperatorSet.GenRandomRegions 有内存泄漏或缓存，释放不掉

开发环境

VS2022 win7 halcon12 halcon18

随机生成100个园

不释放

private void butTemp_Click(object sender, EventArgs e)
         {
             butTemp.Enabled = false;
             HOperatorSet.SetSystem("clip_region", "false");
             {
                 HObject ho_regions;
                 HOperatorSet.GenRandomRegions(out ho_regions, "circle", 10, 20, 10, 30, -0.7854, 0.7854, 1000*1000, 5210, 5210);
                 int iObjNum = WHCSHalCon.Base.CountObj(ho_regions);
                 // regions.Dispose();     
             }
             butTemp.Enabled = true;
         }

内存大约增加900M。

释放

private void butTemp_Click(object sender, EventArgs e)
         {
             butTemp.Enabled = false;
             HOperatorSet.SetSystem("clip_region", "false");
             {
                 HObject ho_regions;
                 HOperatorSet.GenRandomRegions(out ho_regions, "circle", 10, 20, 10, 30, -0.7854, 0.7854, 1000*1000, 5210, 5210); 
                 ho_regions.Dispose();     
             }
             butTemp.Enabled = true;
         }

似乎没效果，内存还是增加了900M。

不裁剪，宽高限定为521

private void butTemp_Click(object sender, EventArgs e)
         {
             butTemp.Enabled = false;
             //HOperatorSet.SetSystem("clip_region", "false");
             {
                 HObject ho_regions;
                 HOperatorSet.GenRandomRegions(out ho_regions, "circle", 10, 20, 10, 30, -0.7854, 0.7854, 1000*1000, 521, 521); 
                 ho_regions.Dispose();     
             }
             butTemp.Enabled = true;
         }

似乎没效果，内存还是增加了900M。

宽高限定为512

除生成的区域数量外，全部用halcon样例的默认值。
