           Summary: SIGABRT or hang on serializing uninitialised
                    RuntimeXxxxHandle
           Product: Mono: Runtime
           Version: 1.9.0
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: misc
        AssignedTo: mono-bugs at lists.ximian.com

Unlikely to be done but serializing an uninitialised
RuntimeTypeHandle/RuntimeFieldHandle/RuntimeMethodHandle causes a crash or
hang.
[[
using System;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

class RuntimeHandlesDefaultSerialize
{
    static void Main()
    {
        System.IO.MemoryStream strm = new System.IO.MemoryStream ();
        BinaryFormatter fmtr = new BinaryFormatter ();
        //
        RuntimeTypeHandle th = new RuntimeTypeHandle ();
        RuntimeFieldHandle fh = new RuntimeFieldHandle ();
        RuntimeMethodHandle mh = new RuntimeMethodHandle ();
        //
        fmtr.Serialize(strm, th);
        fmtr.Serialize(strm, fh);
        fmtr.Serialize(strm, mh);
    }
}
]]

First causes a 100% CPU hang, second and third cause a crash.

On MSFT each fails with a similar exception:
[[
System.Runtime.Serialization.SerializationException: Object fields may not be
properly initialized.
   at System.RuntimeTypeHandle.GetObjectData(SerializationInfo info,
StreamingContext context)
   … ...
]]
