+Summary: Using void as type parameter crashes runtime
+
+Description of Problem: Using void as a type parameter for a generic type
+compiles fine but crashes the runtime.
+
+
+Steps to reproduce the problem:
+1. cat > test.cs << EOF
+class A<T> {
+  public static void Print() {
+    System.Console.WriteLine (typeof(T));
+  }
+  
+  public static void Fun() {
+    T x;
+  }
+}
+
+class M {
+  public static void Main() {
+    A<void>.Print(); // Works
+    A<void>.Fun(); // Crashes
+  }
+}
+EOF
+2. gmcs test.cs
+3. mono test.exe
+
+Actual Results:
+System.Void
+
+** ERROR **: unknown type 0x01 in type_to_stind
+aborting...
+
+
+Expected Results:
+I don't know wether void is allowed as a type parameter. However, the code
+should either refuse to compile or it should run cleanly.
+
+How often does this happen? 
+always
+
+Additional Information:
+I'm using mono 1.1.9
