    when I modify the code as follows, the crash is gone。

    It seems that the string from the `asset_child` is collected by GC when passing to the dictionary as a parameter.

    Code (CSharp):
    1.         while (iter.MoveNext()) {
    2.             var bundle = iter.Current.Value;
    3.             var ab = bundle.assetBundle;
    4.             var asset_child = ab.GetAllAssetNames();
    5.             var scene_child = ab.GetAllScenePaths();
    6.             for (int j = 0; j < asset_child.Length; j++) {
    7.  -                var s = (string)asset_child[j];
    8. +                var s = (string)asset_child[j].Clone();
    9.                 var a = new Asset(bundle, s);
    10.                 name_to_asset[s] = a;
    11.             }
    12.             for (int j = 0; j < scene_child.Length; j++) {
    13.  -                var s = (string)asset_child[j];
    14. +                var s = (string)asset_child[j].Clone();
    15.                 name_to_asset[s] = a;
    16.             }
    17.             bundle.unload(true);
    18.         }

    Bit outside of my skillset, but could you check memory usage? Maybe the first code causes a memory leak?
    If memory usage for both is fine I suggest filing a bug report with the original code (so if it's an actual Unity issue they can fix it) and use the new working one for production.

    I profile the memory usage of the process via Android Studio, the process only used 380MByte.
