+Summary: rethrown exceptions lose original stack trace
+
+Exceptions that get rethrown via "throw;" in a handler lose the actual
+origin stack trace under mono, but do not under the MS runtime. Sample code:
+
+--- bug29.cs ---
+using System;
+public class Driver {
+        public static void Frob () {
+                throw new NotImplementedException();
+        }
+        public static void Bar () {
+                try {
+                        Frob();
+                } catch (Exception e) {
+                        Console.WriteLine ("Exception!");
+                        throw;
+                }
+        }
+        public static void Main () {
+                Bar();
+        }
+}
+--- end ---
+
+Under the MS runtime, this prints:
+$ ./ex
+Exception!
+
+Unhandled Exception: System.NotImplementedException: The method or
+operation is not implemented.
+   at Driver.Frob()
+   at Driver.Bar()
+   at Driver.Main()
+Unknown signal 79
+
+Under mono:
+vladimir@river[1003]% mono bug29.exe
+Exception!
+
+Unhandled Exception: System.NotImplementedException: The requested feature
+is not implemented.
+in <0x0002f> Driver:Bar ()
+in <0x00007> Driver:Main ()
+
+The Frob() frame is lost.
