Unreal Engine Issues and Bug Tracker (UE-77900)

Description

Adding elements to a TMap<int32, int32> causes the editor to crash if the TMap has a default value associated with it.

Tested in 4.22 (CL - 4753647), 4.23 (CL - 7445012), 4.24 (CL - 7605614)

Steps to Reproduce

Load up the QAGame project.
Open QATestActor.h.
Change the UCLASS() to UCLASS(BlueprintType).
Add the following to the end of the class:

 public:
    UPROPERTY(EditAnywhere, Category=Test)
    TMap<int32, int32> Map;

Open QATestActor.cpp.
Add the following to the end of the constructor:

 if (HasAnyFlags(RF_ClassDefaultObject | RF_ArchetypeObject))
 {
    Map.Add(1, 2);
 }

Compile and run QAGameEditor.
Make a Blueprint Actor from the QATestActor class
Add an element to the Map variable

Expected: A new TMap of type <int32, int32> would be created

Result: The engine crashes with the following assert:

Assertion failed: LogicalIdx >= 0 && LogicalIdx < Num() [File:E:\Dev-Core\Engine\Source\Runtime\CoreUObject\Public\UObject/UnrealType.h] [Line: 3275]
