Just to clarify, the LD_PRELOAD part does induce crashes with WoW for me, including a 100% crash in the Launcher.exe. So I run without it, and without any wine debug.
The ldpreload part is to force GW2 to use pthreads - I was getting no difference with just the __GL_THREADED_OPTIMISATIONS part, so I read through the documentation included and found something saying that programs that don't use pthreads can be forced to, using the LD_PRELOAD line that I used.
It looks like this is (thus far) going to be a very case-by-case type of thing.
