Hello,

I’m developping a LAN multplayer VR game with spatialized voicechat using OnlineSubsystemNull. Sometimes, a player randomly crashes on joining the game. The log says :

[2018.10.17-12.19.39:551][402]LogWindows: Error: === 
    Critical error: ===
    [2018.10.17-12.19.39:551][402]LogWindows: Error: 
    [2018.10.17-12.19.39:551][402]LogWindows: Error: Fatal error!
    [2018.10.17-12.19.39:551][402]LogWindows: Error: 
    [2018.10.17-12.19.39:551][402]LogWindows: Error: Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x000006c0

On inspecting the generated .dmp file, it appears that the crash happens in VoiceEngineImpl.cpp line 515

if (RemoteData.VoipSynthComponent->IsIdling() && RemoteData.bIsActive)

Here is my voice initialization process :

  • bRequirePushToTalk = true
  • StartNetworkedVoice manually called on MyPlayerController BeginPlay (if local)
  • CreateTalkerForPlayer called in MyPawn’s OnRep_PlayerState (if not local and if HasActorBegunPlay(), otherwise called again in BeginPlay() )

Do you have an idea of what could cause this crash ?

Thanks,
Ben
