Loading <http://www.apple.com/pr/library/2008/12/16macworld.html> in a 64-bit build of TOT will cause a crash. The following JavaScriptCore regression tests are also failing in 64-bit: ecma_2/String/match-001.js ecma_3/RegExp/perlstress-002.js js1_2/regexp/interval.js js1_2/regexp/string_search.js js1_2/regexp/test.js The root cause is the same.

<rdar://problem/7033448> The following is sufficient to reproduce the crash: 'http://www.apple.com/pr/library/2008/12/16macworld.html'.match(new RegExp('apple.com\\/(\\w{2}|befr|benl|chfr|chde|asia|lae)\\/welcomescreen'))
