Apparently http://trac.webkit.org/changeset/103354 is specific to Mac so we can cross that out.

It seems very unlikely that either http://trac.webkit.org/changeset/103358 or http://trac.webkit.org/changeset/103365 can cause Windows-specific memory regression.

Given that I think http://trac.webkit.org/changeset/103356/trunk/Source/JavaScriptCore/wtf/Vector.h is the culprit. I don't see why it can cause memory use increase unless the compiler is generating bad code but then I wouldn't be surprised if that were the case since the comment being removed says it used to cause a compilation error.
