New issue 3100 by [email protected]: RegEx is hanging in Chrome 31.0.1650.63
http://code.google.com/p/v8/issues/detail?id=3100
Run the following Javascript in the Chrome developer console:
var s
= "aa ,
aa ,
aa ,
aa,
aa,
aa, aa";
console.log(new RegExp('(\\s*\\w+\\s*,\\s*)*bb', 'i').exec(s));
Now run the same command in FireFox and notice that it finished instantly.
Of course, the RegEx is not a good RegExp, so I wouldn't be surprised if
you never this bug. I just wanted to make v8 aware of the performance
problem. The RegExp can be fixed by changing it to '(\\s*\\w+\\s*,)*\\s*bb'
which should have the same effect.
