Mangos: [10984] (first appeared with [10923])

SD2: 1933

System: Mac OS X, 10.6.5, gcc 4.2.1

Since a few days I am getting regular crashes while being in combat. I could reproduce the crash with both crash logs listed here: http://pastebin.com/iV6i9dUB. In short this is what gdb shows after the crash:

1190                originalCaster = triggeredByAura->GetCasterGuid();

The second time it was exact the same method call (different parameters) that caused the crash (as written above, complete logs at pastebin).

Please have a look at this and contact me if you need more data or logs (server, world, etc).

Thanks in advance.

[10987] must fix problem.

After a few hours in-game without any crash I can absolutely confirm this.

Thanks a lot, again!

Cheers,
