http://bugs.winehq.org/show_bug.cgi?id=50824 --- Comment #9 from Federico Dossena <info@fdossena.com> --- I had AI take a look at it and after half a day it found the cause and a potential workaround. The issue is caused by unarc doing something really silly: a binary search to find the largest VirtualAlloc that doesn't fail, starting with a 2GB that normally fails on windows (and on 32 bit wine), but for some reason succeeds on wow64 wine, causing an overflow inside unarc. The "fix" is the attached workaround, which simply makes all allocations requests >=2GB fail for 32 bit applications. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
