The following testcase asserts on ionmonkey revision 23a84dbb258f (run with --ion -n -m --ion-eager):


test();
function test() {
  enterFunc ('test');
  var whitespace = [
    {s : '\u0009', t : (00  )},
    {s : '\u000B', t : 'VERTICAL TAB'},
    {s : '\u000C', t : 'FORMFEED'},
    {s : '\u0020', t : 'SPACE'},
    {s : '\u00A0', t : 'NO-BREAK SPACE'},
    {s : '\u1680', t : 'OGHAM SPACE MARK'},
    {s : '\u2006', t : 'SIX-PER-EM SPACE'},
    {desc : '\u2007', t : 'FIGURE SPACE'},

    ];
  for (var i = 0; i < whitespace.length; ++i)
    reportCompare(true, !!(/\s/.test(v.s)), 'Is ' + v.t + ' a space');
}

Wasn't able to reproduce this on the original revision. Assuming that the repo wasn't clean and closing as WFM.
