New issue 2655 by [email protected]: Matching a particular regular
expression causes hang/freeze!
http://code.google.com/p/v8/issues/detail?id=2655
This is hard to believe. Run this in Chrome or Node:
"https://www.dropbox.com/sh/oijdfs1uhn3zi6y/DoiUdfIpPE?m".match(/^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w
\.-]*)*\/?$/)
Node will hang. Chrome will hang if this JS is in a page. If in the
console, the console will proceed to the next line right away, but you'll
never see a result, and what you pasted won't be in the input history (e.g.
if you press up).
Tested in Node 0.10, Node 0.6, and Chrome 26 across three different
machines, all Mac OS X, but both 10.7 and 10.8.
I've randomly changed the characters of the Dropbox URL, but maintained
their character classes (lowercase letter, uppercase letter, number). If I
change the URL more, it seems to work, so there's something about this type
of URL and/or the regular expression.
