+Summary: error in stack constructor
+
+Error in both mcs and gmcs version mono-1.1.8
+compiled from source using ./configure --prefix=/usr/local, make, sudo make
+install.
+Operating system Linux Ubuntu Hoary 5.0.4
+
+// vim:sw=4:ts=8
+using System;
+using System.Collections;
+
+public class Test
+{
+    static void Print (ICollection c)
+    {
+	Console.Write ("[{0,2} items]:", c.Count);
+	foreach (bool b in c) {
+	    Console.Write ("{0} ", b ? "1" : "0");
+	}
+	Console.WriteLine ();
+    }
+
+    public static void Main()
+    {
+	bool[] bools = {true, false, true};
+	BitArray b = new BitArray(bools);
+	/*
+	ArrayList b = new ArrayList(bools);
+	*/
+	Stack s = new Stack (b);
+	Print (s);
+    }
+}
+
+when compiled and run produces error:
+
+Unhandled Exception: System.ArgumentException: array
+Parameter name: Unsupported type
+in <0x0029f> System.Collections.BitArray:CopyTo (System.Array array, Int32
+index)
+in <0x000a0> System.Collections.Stack:.ctor (ICollection col)
+in <0x00096> Test:Main ()
+
+if one comments the BitArray line and uncomments the ArrayList line the
+program runs correctly and produces
+[ 3 items]:1 0 1
+
+running monodis on the two exes produces the following differences (same in
+mcs as well as in gmcs apart from line numbers):
+
+11c11
+< .module Test.exe // GUID = {8903F511-BA65-4D57-BA69-8CC574A40ECA}
+---
+> .module Test.exe // GUID = {CD8419A2-FAF3-4231-A573-A38517EF333F}
+98c98 (99c99 for mcs)
+<               class [mscorlib]System.Collections.ArrayList    V_1,
+---
+>               class [mscorlib]System.Collections.BitArray     V_1,
+116c116 (117c117 for mcs)
+<       IL_0014:  newobj instance void class
+[mscorlib]System.Collections.ArrayList::.ctor(class
+[mscorlib]System.Collections.ICollection)
+---
+>       IL_0014:  newobj instance void class
+[mscorlib]System.Collections.BitArray::.ctor(bool[])
+
+
+happens always:
+
+Hope this helps
