the error seems to have appeared in the last couple days checkins. The given
|
|
test class doesnt compile on mono but does on windows and used to compile on
|
|
mono a few days ago.
|
|
|
|
1. Test Class:
|
|
using System;
|
|
using System.Collections.Generic;
|
|
|
|
namespace Test
|
|
{
|
|
internal struct TestClass4<T> : IEquatable<TestClass4<T>>, IEquatable<T>,
|
|
IEqualityComparer<TestClass4<T>> where T : class
|
|
{
|
|
public bool Equals(T obj)
|
|
{
|
|
return true;
|
|
}
|
|
|
|
public bool Equals(TestClass4<T> entry)
|
|
{
|
|
return true;
|
|
}
|
|
|
|
public bool Equals(TestClass4<T> x, TestClass4<T> y)
|
|
{
|
|
return x.Equals(y);
|
|
}
|
|
|
|
public int GetHashCode(TestClass4<T> obj)
|
|
{
|
|
return obj.GetHashCode();
|
|
}
|
|
|
|
public override int GetHashCode()
|
|
{
|
|
return 1;
|
|
}
|
|
|
|
public override bool Equals(object obj)
|
|
{
|
|
return false;
|
|
}
|
|
|
|
public static bool operator ==(TestClass4<T> entry1, TestClass4<T>
|
|
entry2)
|
|
{
|
|
return entry1.Equals(entry2);
|
|
}
|
|
|
|
public static bool operator ==(T entry1, TestClass4<T> entry2)
|
|
{
|
|
return entry2.Equals(entry1);
|
|
}
|
|
|
|
public static bool operator ==(TestClass4<T> entry1, T entry2)
|
|
{
|
|
return entry1.Equals(entry2);
|
|
}
|
|
|
|
public static bool operator ==(object entry1, TestClass4<T> entry2)
|
|
{
|
|
return entry2.Equals(entry1);
|
|
}
|
|
|
|
public static bool operator ==(TestClass4<T> entry1, object entry2)
|
|
{
|
|
return entry1.Equals(entry2);
|
|
}
|
|
|
|
public static bool operator !=(TestClass4<T> entry1, TestClass4<T>
|
|
entry2)
|
|
{
|
|
return !(entry1 == entry2);
|
|
}
|
|
|
|
public static bool operator !=(T entry1, TestClass4<T> entry2)
|
|
{
|
|
return !(entry1 == entry2);
|
|
}
|
|
|
|
public static bool operator !=(TestClass4<T> entry1, T entry2)
|
|
{
|
|
return !(entry1 == entry2);
|
|
}
|
|
|
|
public static bool operator !=(object entry1, TestClass4<T> entry2)
|
|
{
|
|
return !(entry1 == entry2);
|
|
}
|
|
|

public static bool operator !=(TestClass4<T> entry1, object entry2)
|
|
{
|
|
return !(entry1 == entry2);
|
|
}
|
|
}
|
|
}
|
|
|
|
|
|
2. compile it:
|
|
gmcs /targe:library test4.cs
|
|
