Description Lóránt Dobos 2014-04-14 10:33:47 UTC
using System;
public static class Program
    public static void Main()
        Console.WriteLine("{0}", Lib.Foo<object>());

using System;
public static class Lib
    public static T Foo<T>(T x = default(T))
        return x;

dmcs -t:library bug2lib.cs; dmcs bug2.cs -r:bug2lib.dll; ./bug2.exe

expected result is null but it prints System.Reflection.Missing.
It works if compiled together (dmcs bug2.cs bug2lib.cs)
