NGUI crash when Take Detailed Memory Sample from Profiler in android device

[yuewah]

I am using Unity 4.5.4, Window 7 64bit, NGUI 3.7.3

when I instantiate either Prefab 1 or Prefab 2 around several thousand clone, it crash in the android device when I am going to take detailed memory sample from profiler.

Prefab 1 ( active = false )
|- Sprite ( UISprite , active = false )

Prefab 2 ( active = false )
|- Label ( UILabel , active = false )

It does't crash when using other simple script, e.g. UIWidget, UIButton etc.
It does't crash in iOS device
It does't crash in PC standalone

All I can suggest is report it to Unity. Anything crash related is Unity, not NGUI.

Yes, I will report it to Unity with a simple project containing NGUI script.
