title: Xamarin crashing on build with Compiler crashed code 1
body: <p>I have installed Xamarin and am trying to build my first solution.</p>
  
  <p>So far I have created the new solution, then tried to build and run it. It's blank so I would expect it to at least compile.</p>
  
  <p>Unfortunately I'm getting the error 'Compiler crashed code 1'.</p>
  
  <p>So far I have reinstalled the Mono Framework and changed the MCS file to reference versions/current as found <a href="http://forums.xamarin.com/discussion/30097/task-csc-execution-failed-xs-on-mac-os-x-yosemite" rel="nofollow">here</a>.</p>
  
  <p>The full error is:</p>
