Crash when running redos

[pushkin-]

I get a crash for some files when running this:

find . -name "*.js" -not -path "./node_modules/*" -exec redos {} \;

TypeError: Cannot read property 'regex' of undefined

Looks like it stems from here:

traverse( ast, function(node) {
    if (node.regex && node.regex.pattern)
      regexNodes.add( new Node(node) );
  });
