Bug / Crash App crash after RemoveFromSolver called [4.0.2 and older]

[mmortall]

During my debugging I was able to find that there are some problems with memory deallocation. 
I will write in this post all I will find

Double deallocation here. I got it twice.

Code:

Trying to UnpinMemory for already unpinned handler
UnityEngine.Debug:LogError(Object) (at ?)
Oni:UnpinMemory(GCHandle) (at Assets/Plugins/Obi/Scripts/Oni.cs:454)
Obi.MeshDataHandles:FromMesh(Mesh) (at Assets/Plugins/Obi/Scripts/Collisions/ColliderTrackers/Trackers3D/ObiMeshShapeTracker.cs:30)
Obi.ObiMeshShapeTracker:UpdateMeshData() (at Assets/Plugins/Obi/Scripts/Collisions/ColliderTrackers/Trackers3D/ObiMeshShapeTracker.cs:92)
Obi.ObiMeshShapeTracker:.ctor(MeshCollider) (at Assets/Plugins/Obi/Scripts/Collisions/ColliderTrackers/Trackers3D/ObiMeshShapeTracker.cs:59)
Obi.ObiCollider:CreateTracker() (at Assets/Plugins/Obi/Scripts/Collisions/ObiCollider.cs:73)
Obi.ObiColliderBase:AddCollider() (at Assets/Plugins/Obi/Scripts/Collisions/ObiColliderBase.cs:129)
Obi.ObiCollider:set_SourceCollider(Collider) (at Assets/Plugins/Obi/Scripts/Collisions/ObiCollider.cs:28)
Obi.ObiCollider:Awake() (at Assets/Plugins/Obi/Scripts/Collisions/ObiCollider.cs:109)
UnityEngine.GameObject:AddComponent() (at ?)

Add to solver after removefromsolver:

Code:

UnityEngine.Debug:LogError(Object) (at ?)
Oni:UnpinMemory(GCHandle) (at Assets/Plugins/Obi/Scripts/Oni.cs:454)

Obi.ObiCloth:AddToSolver(Object) (at Assets/Plugins/Obi/Scripts/Actors/ObiCloth.cs:180)

Code:

Code:

Obi.ObiCollider:set_SourceCollider(Collider) (at Assets/Plugins/Obi/Scripts/Collisions/ObiCollider.cs:27)

Hope it helps. For now I will just ignore this deallocation requests. There are around 4-6 of them and I don't see a significant memory leaks
