+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.

+
+This occurs with Mono 1.0 on Windows and Linux (XP SP2 and FC2)
+
+Use the following code:
+
+// Following works
+double x = 1.0;
+Console.WriteLine(x.ToString("00.00E00");
+
+// Following doesn't work
+double  y = 0.0;
+Console.WriteLine(x.ToString("00.00E00");
+
+Steps to reproduce the problem:
+1. use the above code snippet
+2. compile with mcs
+3. run with mono
+
+Actual Results:
+Unhandled Exception: System.IndexOutOfRangeException: Array index is out of
+range.
