Regular Expression Test Executes Incorrectly

[ghost]

var str = 'table football';

var regex = new RegExp('foo*');
var globalRegex = new RegExp('foo*', 'g');

alert(globalRegex.test(str));
alert(globalRegex.test(str));

This code alerts true and true. Which is incorrect, it's suppose to alert true and false.

I've not looked at the code, but this smells of .lastIndex not being updated correctly.

Confirmed. Here's a minimal test:

var r = /foo*/g;
r.test('table football');
alert(r.lastIndex); 

This should alert 9, but JS-Interpreter alerts 0.
