If two code components have the same TEXT("") name in the CreateDefaultSubobject call the code will compile correctly but the editor will freeze when adding an instance of the class or classBP to the level.

Steps to Reproduce

1. Open UE4Editor (any project)
2. Add Code to project based on Actor (MyActor)
3. In MyActor.h add the following:

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Test)
UShapeComponent* Box;

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Test)
UShapeComponent* Box2;

4. In MyActor.cpp Add the following to the constructor:

Box = CreateDefaultSubobject<UBoxComponent>(TEXT("Box"));
Box2 = CreateDefaultSubobject<UBoxComponent>(TEXT("Box"));

5. Compile
6. Add class instance to the level

When the instance is added to the level and construction script runs the editor freezes

Compile error referencing naming conflict
