OOS issues in multiplayer

[Bitron]

I got a bunch of OOS messages and some errors today when playing multiplayer matches with/against both human players and computer (2hv2ai). We played with UMC first, but got those errors so we decided to go with standard. Still the same.

This is one of the errors I got:

hmm i just played a game on the official mp server using 2 clients and didn't get any erros, also unfortuanteley the erromessage is rather generic and doesn't contain much information.

So please
1) I't be nice if you could generate a stacktrace, i don't think the current wesnoth windows releases support that so you'd need to build wesnoth yoursel to do this. I understand if you won't so it but it'd mostlikeley bevery helpful.
2) Are you sure there are no addons involved ? there are afaik some some 'bad' addons that alter the gamestate even if you don't have them activated. please (you and your opponent) rename your wesnoth preferences directory, then restart wesnoth and try again.
3) If (1) is not possibel and you used (2) to ensure that this is not caused by an addon please upload your and your opponents replay savefiles for that match.

I do have a few addons installed, but I had them installed for a while now and the error never occurred before. I'll try to re-create the issue, without any addons installed.

installed addons:

A_New_Home
A_Vilkish_Tale
Archaic_Resources
Intriques
Vilkai_Era

Two things I remember:
- There was a download running in the background (gog galaxy)
- I lowered the game speed mid game

I't be nice if you could generate a stacktrace

I recently build Wesnoth myself successfully, so I actually could do that. Not sure how to 'generate a stacktrace' though. But there was a "how to" somewhere in the forums if I recall it right, so I will have a look at it right away.
Edit: Had a look at it. Not sure how to do that with Visual Studio. I'm not a real programmer, just curious.

And here is the Replay:

thx, unforteuneteley i could not reproduce any crashes with that replay, and some OOS. I did get some other unreelated erro though for which i file d abugreport.

you know the same about your opponent/ally ?

[Bitron]

you know the same about your opponent/ally ?

My opponent/ally had just installed Wesnoth 1.13.8 and downloaded one addon, the one we wanted to play in the first place. It was the vilkai era.
I updated that era just today, but it was just balancing, no significant changes.

[gfgtdf]

hmm ok then it inded sounds like a core bug.

it'd be nice if you coudl eigher give a step-by-step instruction how to reoproduce or a stacktrache. Also it's important to know whethe ryou did one of the folling things that were known to casue OOS in the past:
1) Reload an mp game
2) change controllers during the game
3) droid/undroid the sides during the game.

but it was just balancing, no significant changes.

generally balanching changes can cause OOS, in case that you and your friend had missmatching versions of the addons but since the the oos also happened in mainline i assume that this is not the cause.

A_New_Home
A_Vilkish_Tale
Archaic_Resources
Intriques
Vilkai_Era

those sounds quite harmless i was thinking more about addons like some alterntive random mode things.

- There was a download running in the background (gog galaxy)
- I lowered the game speed mid game

Sounds harmess aswell.

Edit: Had a look at it. Not sure how to do that with Visual Studio. I'm not a real programmer, just curious.

To generate a stacktrace you usually have to
1) build wesnoth with debug symbols, it'S quite possibel that our default wesnoth msvc releade build (which i recocmend to use) doesnt create dbug symbold in that case you have to change it in the porjectsettings.
2) Now that you have wesnoth.exe with debug symbols start wesnoth in debug mode, usually pessing F5 from visual studio should do that.

[Bitron]

1) Reload an mp game
2) change controllers during the game
3) droid/undroid the sides during the game.

Nopes to all three of them.

build wesnoth with debug symbols

What are debug symbols and where do I find them?

[gfgtdf]

Since my local copy of viaul studio won't start anymore i cannot tell for sure, but i think its something like project explorer-> rightlick wesnoth -> project settings -> Debug -> Denerate debug info -> yes
