Hi.

I have a c++ class with TArray< TSubclassOf < USomeClass > > uproperty in it. This array is filled with some blueprints based on C++ UObject class. Everything works fine in the PIE, but game crashes on iPad launch, logs says:

Loading .../Content/Maps/ConceptMap.umap

UE4Editor(2557,0x7fff723cb310) malloc: *** error for object 0x10d719c00: Invalid signature for pointer dequeued from free list

By the way, when the array is empty, game launches correctly. Is this a known issue?

full log is here: https://dl.dropboxusercontent.com/u/83133453/Tarray_TSubclassOf_crashlog.txt

UE 4.3.0, Launcher based

Mac OS X 10.9.4 Xcode 5.1.1 iPad Air, iOS 7.1.2

Sorry for my bad English.

Hi rxl,

I am very sorry that we did not take a look at this sooner. Is this something that you are still having trouble with in the latest released version of the Engine?
