New issue 2886 by [email protected]: Handling specific regular expression
http://code.google.com/p/v8/issues/detail?id=2886

Executing the following code, takes forever:

"Hello there, very best wishes, from Syria...".match(/^((?:, |[\w ]+)+)$/);

while executing the following, takes a little bit less than ever, but a little bit more than ten seconds!

"Hello there, best wishes, from Syria...".match(/^((?:, |[\w ]+)+)$/);

...and then it returns null

Tried on my Ubuntu 12.04 64-bit machine, Archlinux 32-bit server and a Debian Wheezy 32-bit server, all of which running node v0.10.18.

Bug first observed on node.js, but tests on mongo shell (that uses v8) and Chrome's console shows the same behaviour.
