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
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-69912 in the post.
