v8

Im using this regex to get the contents of a tag in a file.

var regex = new RegExp("<tag:main>((?:.|\\s)*)</tag:main>");

This causes the v8 engine to hang indefinitely.

Now, if I use new RegExp("<tag:main>([\s\S]*)</tag:main>"), all is good.

Anyone have an idea why the first one takes too long?
