tables/mozilla/bugs/bug33855.html is failing because of this change in StringImpl.cpp in r18098: - return c <= 0x7F ? isspace(c) : (u_charDirection(c) == U_WHITE_SPACE_NEUTRAL); + return c <= 0x7F ? isspace(c) : WTF::Unicode::isSpace(c);
Fixed by Hyatt in r18161 and r18162. http://trac.webkit.org/projects/webkit/changeset/18161 http://trac.webkit.org/projects/webkit/changeset/18162
