How to crash Google Chrome

Google claims that its browser Google Chrome is able to isolate events that may crash a browser, isolated within those individual tabs. However, an issue exists with how Google Chrome handles undefined handlers in chrome.dll version which is the latest version of the browser. A crash can result without any user interaction.

When a user visits a malicious link which has an undefined handler and followed by a special character, the browser crashes. You can also crash the browser by typing the characters :% in the Chrome URL bar. Google Chrome crashes with a message ” Whoa! Google Chrome has crashed. Restart now?”
