+Summary: value is or prints as nan with mono, not with mint
+
+The following CS program produces different results run with mono and mint.
+The mint result is correct.  I have not been able to simpify it any further.
+
+Happens with 0.15-1 and 0.16-1
+
+---------------------------------(fbug.cs)--------------------------------
+
+using System;
+
+class fbug
+{
+    const int REPS = 100;
+    const int LEN =  10;
+
+    public static void Main(String[] args)
+    {
+        double[] x = new double[LEN];
+
+        for (int i = 0; i < LEN; i++) x[i] = i+1;
+
+        double s = Environment.TickCount;
+
+        for (int i = 0; i < REPS; i++) sum(LEN, x);
+
+        //without this line mono prints elapsed time as nan. Mint does not.
+        //double elapsed = Environment.TickCount - s;
+
+        Console.WriteLine("Time = {0} Seconds",
+                          (Environment.TickCount - s) / 1000.0);
+    }
+
+    static double sum(int n, double[] x)
+    {
+        double val = 0.0;
+        for (int i = 0; i < n; i++)
+            val += x[i];
+        return val;
+    }
+}
+---------------------------------(fbug.cs)--------------------------------
+
+Compile with
+
+    mcs fbug.cs
+
+run with mono:
+
+   luke@nokomis2 speed% mono fbug.exe
+   Time = nan Seconds
+
+run with mint:
+
+   luke@nokomis2 speed% mint fbug.exe
+   Time = 0.005 Seconds
+
+Uncomment the marked line, recompile and mono and mint both behave correctly
