            Bug ID: 43425
           Summary: 64-bit .NET application crashes with
                    NullReferenceException
           Product: Wine
           Version: 2.12
          Hardware: x86-64
                OS: Linux

back trace of the bug

I encountered a problem with the 64-bit .NET Framework: 

My C# program is very simple: 

Code:
static void Main(string[] args)
{
    System.Console.WriteLine("Hello world!");
    Debug.WriteLine("Debug Hello world!");
}


I installed the WINE-2.12 64-bit on CentOS 7 (3.10.0-514.21.1.el7.x86_64) and
installed the .NET Framework 4.6.1 onto it. Before installing the .NET
Framework, I removed wine-mono. I got the following error message when I tried
to run the above program:


Hello world!

Unhandled Exception: System.NullReferenceException: Object reference not set to
an instance of an object.
at System.Diagnostics.DiagnosticsConfiguration.Initialize()
at System.Diagnostics.DiagnosticsConfiguration.get_IndentSize()
at System.Diagnostics.TraceInternal.InitializeSettings()
at System.Diagnostics.TraceInternal.WriteLine(String message)
at ConsoleApplication3.Program.Main(String[] args)
wine: Unhandled page fault on read access to 0x00000000 at address 0x1aa460fd
(thread 0009), starting debugger...


The problem is with the line "Debug.WriteLine(...)". However, the same
application compiled with 32-bit works well.

I found out that I got the similar error at other positions when I ran our
in-house 64-bit .NET program, even if I don't use Debug.WriteLine(...), so I
created the hello-world program to reproduce it. 

My final goal is: run our 64-bit .NET application on a 64-bit WINE with .NET
Framework 4.6.1.
