1. compile this using gmcs
using System;
using System.Reflection;
public class C
{
public static void Main (string[] args)
{
Assembly a = Assembly.LoadFile (args[0]);
Console.WriteLine (a.FullName);
Print (a.GetType ("System.Attribute"));
Print (a.GetType ("System.Int32"));
Print (a.GetType ("System.Int64"));
}
static void Print (Type t)
{
Console.WriteLine (t.FullName);
Console.WriteLine (t.Assembly.FullName);
}
}
2. run using enclosed assembly
mono test-1000.exe mylib.dll
Expected results:
mylib, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
System.Attribute
mylib, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
System.Int32
mylib, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
System.Int64
mylib, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
Actual results:

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
