After some investigation (using interesting users dumps at and in many others places)

looks like more an ugly WoW bug

For example seeing this typilical error:

This application has encountered a critical error:

ERROR #132 (0x85100084)
Program:	C:\Program Files\World of Warcraft\WoW.exe
Exception:	0xC0000005 (ACCESS_VIOLATION) at 001B:00650E16

The instruction at "0x00650E16" referenced memory at "0x33991588".
The memory could not be "read".

While registers was:

EAX=00000001  EBX=13991500  ECX=00A49658  EDX=00000003  ESI=1399155C
EDI=00000000  EBP=0012FC58  ESP=0012FC38  EIP=00650E16  FLG=00210202
CS =001B      DS =0023      ES =0023      SS =0023      FS =003B      GS =0000

The must interesting is that error address was always (EBX + 0x20000000) + 
something little (usually between 0x10-0x88). 

for info 0x20000000 => 512Mb :)

So who go to blizzard to fix the bug ? :)
