Status: New Owner: ---- New issue 1915 by [email protected]: v8 locks up on regex matching http://code.google.com/p/v8/issues/detail?id=1915
A user of my markdown parser posted an issue today: https://github.com/chjj/marked/issues/23
They mentioned that chrome would lockup whenever they fed it a specific piece of HTML. I managed to track down the lockup to one specific regex. This appears to be a problem with v8: both node.js and chromium begin to use 100% CPU when trying to .exec() this regex, while Spidermonkey/Jaegermonkey/Firefox execute the regex immediately and do not lockup at all.
Here is a link to the regex and string in question: https://gist.github.com/1672262
