Subject: [Slouken] Reproducable ReloadUI client crash |
| |
If you have an AddOn that registers for many events (in this case calls RegisterEvent for the same event multiple times) and you reload the UI a few times, the client will crash when one of your events fires.
Seen this happen quite a few times now. Never happens unless you have done a reload UI (in my experience, only after several reload UI calls).
Seen this in both 1.6.1 and 1.7.0. I can provide minidumps or the actual mod in question, although I'm not willing to post either publicly.
(See posts below for repro scenario + AddOn)

Can you post a link to the crash log in the Errors directory?

Q u o t e:
function WowCrashTest_RegisterEventCrash()
for i = 0, 1000 do
this:RegisterEvent("CHAT_MSG_CHANNEL");
end
end
By the way, it's unlikely that the loop is the cause. When you register for an event, the game checks to see if you're already registered and ignores it if you are... or should, anyway. :)

Also, look for DBG: in the stack memory dump. The frame currently executing is stuffed there for debugging purposes. :)

What debug environment are you running? I'm not familiar with this output.
This indicates that the game tried to jump to and execute a NULL pointer. I'm not sure how it could do that, unless maybe there's memory corruption of a frame's vtable.
Could you also post a link to the error log for this crash?
This is definitely different from the second crash you posted.[ post edited by slouken ]

These two crashes are completely separate problems, and unrelated to any addons you have. You can get them any time you reload the UI, if the timing is right. Having lots of players around (e.g. in Ironforge) would increase the likelyhood of a crash.
They should be fixed for 1.8, thanks!
