+Summary: Stack problem with params-arguments transfering value types
+
+Following code passing a variable number of value-type arguments to a
+method compiles with mcs-0.16 and mcs-anoncvs20021108 but failes to run
+with mono-0.16 and mono-anoncvs20021108:
+
+class TestCase
+{
+    public struct JValue 
+    { 
+        int val; 
+        public JValue(int i) { this.val = i; }
+	public static implicit operator JValue(int i) { return new JValue(i); }
+    }
+    static void TriggerTheBug(params JValue[] args) {}
+    public static void Main() { TriggerTheBug(new JValue(23)); }
+}
+
+instead of passing code to "TriggerTheBug" this error message followed by a
+NullReferenceException is exposed:
+
+** (testcase.exe:5023): WARNING **: more values on stack at 00
+.TestCase:Main () IL_001f: 1
+ (LDIND_I4 ADDR_L[1])
+
+This problem could be caused by bug 33532. Attached you'll find the binary
+produced by anoncvs version of mcs.
