Crash Log #1, recorded with WINEDEBUG=+relay at Qufim Island Planar Rift prior
to Kaggen spawn

As of the 03/27/2012 Version Update, FINAL FANTASY XI uses a new method of
handling combat effects (particularly Job Abilities and Weapon Skills) to
prevent crashes from occurring in Voidwatch on X-Box 360. These fixes also
apply to the PC version, however, and they've been causing crashes in WINE.

Reproduction:
Crashes seem to occur at random whenever a Weapon Skill or Job Ability is used
in an area with high player and enemy traffic. The crash always happens mid-way
into the effect with up to nine server events buffered after it. (Rough
location of the crash in the game's logfiles can be discovered in Program
Files\PlayOnline\Square Enix\FINAL FANTASY XI\TEMP\0.log after the crash.) More
players in the area will increase the probability of the crash occurring. More
enemies being fought in the area at the same time (particularly larger
enemies/Notorious Monsters with larger ability effects) will also increase
probability.

To Reproduce:
Go to any Planar Rift in which players are currently fighting or are about to
fight a VWNM (guaranteed 10-18 people) for a high chance of seeing this bug in
Free Trial (see below) circumstances.

Tested On:
Gentoo Linux AMD64, using an Nvidia graphics card and nvidia-drivers. However,
reports from the AppDB page lead me to assume this crash is currently happening
across most distros and video cards. (I intend to test this crash on 1.5.1 as
soon as Gentoo gives me an ebuild for it.) Testing for non-subscribers can
probably be carried out using the 30-day free trial at
http://www.finalfantasyxi.com/freetrial/ .

Notes About Attachments:
The first two logs attached to this bug were recorded using only
WINEDEBUG=+relay ; the second two were recorded using only WINEDEBUG=+seh,+tid
. This is due to the fact that +relay reduces the speed of the game to 0.5-1FPS
on my machine and +relay,+seh,+tid all set at once will generate enough lag to
time the game's connection out a few minutes after login.
