Is the new animation system leaking memory in iOS?

Questions & Answers

Hi,

I am making a 2D puzzle game and have some sprites animated with the new animation system (Animator and Animations).
Recently I ran my game on Instruments in Xcode 5 and found some memory leaks.
Every time I load a level (Xcode), Instruments raise the leak count in “Animator” objects of the previous level.
More specifically memory allocated by calls of mecanim::statemachim::CreateStateMemory(…) are not properly released.
I attached a screenshot of Instruments with the referred function highlighted.

I’m using Unity3D 4.3.4f1 free.
Xcode 5.1.1
Running game in iOS 7.1 in a iPad 2 and iPhone 4S devices.
All my scripts are in C#.

I tried using System.GC.Colect(), load level with LoadLevelAdditive(), adding animator dynamically with gameObject.addComponent and got the same result.

Is this really a memory leak?
Is there something I can do to resolve this issue?

The new animation system is awesome and I hope I’m doing something wrong.

Kind regards,

Hi,

I posted this answer some days ago and I tested with the new 4.5 version recently released and the memory leak has reduced dramaticaly if not completely.
I need to do more testing to double check but I consider this resolved.
