Crash in Debug Camera (patch provided in comment !)

Hello,

 

A licensee has reported us a crash in DebugCameraController / DebugCameraHUD.

 It is due to a missing check in ADebugCameraHUD::PostRender() of SelectedActor set in ADebugCameraController::Select.

 

I have made a patch fixing the crash (replace the != NULL by a IsValidLowLevel() to ensure GC status). Please find attached. It is to be appliedin DebugCameraHUD.cpp

 

 

 

I think the same kind of crash might happen with the other variables set in ADebugCameraController::Select() :

SelectedComponent
GDebugSelectedActor
GDebugSelectedComponent

 

• Open the template game First Person
• Launch the game by pressing play in the editor
• Open console command and input ToggleDebugCamera
• Select an Actor by left clicking the mouse
• Input DestroyTarget in the console command
• Wait for the GC to come or input Obj GC in the console command
