the given source compiles on windows .net and mono 2.4.2 but not on the current
source. I think it started failing in mono 2.6

Run gmcs monofail5.cs on this source:

monofail5.cs:
using System;
using System.Collections.Generic;

   public class TestClass1
   {

      private void CantCompileMethod()
      {
     double[] zCoords =
            new double[8 * 3]
               {
                  4.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0,
                  2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0,
                  0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0
               };

      }      
   }

Generates the following error:
Internal compiler error at monofail5.cs(7,20):: exception caught while emitting
MethodBuilder [TestClass1::GetSession]
