[PhilipJFry]

do you have some logs you can post?
instructions are in the red text

[C-Star]

sry, its overwritten already i guess. didnt know that the exception wasnt enough. Will do better in the future.

you may close this as you want.

[Uveso]

Hello C-Star,

we know this bug, but we can't trace it.
This is all we have about this error at the moment:

Code: Select all

In summary:
If this error occurs in multiplayer all players crash simultaneously with the same error (0x005f39f7)
Also happens in single player vs AI
No warnings, game just crashes. One player said he was "issuing orders" before the game crashed.
Only a few replies after first Post. Mostly the error don't returned.

No idea so far, what could cause this.

https://github.com/FAForever/fa/issues/1574

if you can reproduce this error or give us any additional information please do so.

[Fyren]

Have had a similar-sounding error that occurs in each game I've recently attempted to play. In multiplayer, each game starts with a desync, and as soon as the first move/select command is issued the game crashes. Besides the desync other players dont seem to be directly effected by the. Against AI or in Sandbox the game just crashes.

That's a null pointer assignment. Unlikely to be fixable in my opinion.

ETA: 0x005f39f7 isn't the error code, the error code is 0x05 (access violation).

There is a pointer sitting at heap offset 0x005f39f7 which points to null (ie the contents of that memory location is all zeros. The program reads the pointer, requests data from where it points to (nowhere) and boom.

It could be anything. Since lua doesn't use pointers as part of the language specification, it is not due to faulty logic in one of the game's lua files. The error is baked into the exe somewhere; there could be a bug in the lua garbage collector, or anywhere else for that matter... Fock knows.

If it's the garbage collector (and this is just a stab in the dark), maybe reducing or increasing the number of forced GCs might help.

I've never had this problem myself, it might be worthwhile to find out more background info- ie what chipset/cpu/gpu/os etc they're running.

[Uveso]

ETA: 0x005f39f7 isn't the error code, the error code is 0x05 (access violation).

Yes, the error code is 05. And yes, 005f39f7 is the memory address where the error occours:



The same error occours always on the same memory address. So we can trace a bug with it.

And lua can trigger those errors. just look here:

[RocketRooster]

Am I correct in assuming that debugging symbols have been stripped from the compiled binary?
