Old crash with bad mover pointer for charmed creatures

[Auntie Mangos]

Core: 10610 but appear since 9000+ and i always need a hack to fix it. Only appear with high population 1000+ online

Related with corrupted mover pointer at charmed creature... maybe:

http://pastebin.com/8zR3cTDS

With this fix http://pastebin.com/EVhHgrB0 by zergtmn crash less in low population 600 max online

If i check with: http://pastebin.com/CM5eVNPJ crash again in same position

If i remove this antiexploit check, crash later in:

data.appendPackGUID(mover->GetGUID());  

I can only use a really ugly hack checking if plMover is not null, but no relocation for charmed creatures.

And no... i dont use vehicle patch and nothing related with movers

Any ideas to finally fix it?

Best regards

You mean we should use the lighthouse instead? I don't get it.

Mover cannot be null. It is always pointer to some unit or player itself.

Mover cannot be null. It is always pointer to some unit or player itself.

Yes in this case must be related to some other problem or custom patch.

[kero99]

Yes, but in this crash mover is not NULL, i test with a ASSERT to check NULL pointer in mover but is not the case, mover is simply corrupted only in some cases where mover is from a unit not player.

New version of crash with rev 10732

crash logs not help in this case. mover corrupted in different packet handler some time before crash affected handler called.

So crash log not have any useful info for external viewer. In like case can be help only repeatable way reproduce crash.
