Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

TArray< TSubclassOf < USomeClass > > crashes on iPad


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?
