[Pnet-developers] [bug] CultureInfo constructor crashes

[Bruno Haible]

Using pnet-0.6.0.

Here are two crashes of CultureInfo constructors:

1) When trying to create a CultureInfo equal to the default locale:
==================== hello.cs =======================
using System;
using System.Globalization;
class Hello {
  static void Main() {
    new CultureInfo("de-DE");
  }
}
=====================================================

$ cscc hello.cs -o hello.exe
$ LANG=fr_FR ilrun hello.exe
; ok, no error
$ LANG=de_DE ilrun hello.exe
Uncaught exception: System.ArgumentException: Es gibt bereits einen Eintrag mit 
dem angegebenen Schluessel

        at System.Reflection.ClrMethod.Invoke(Object, BindingFlags, Binder, 
Object[], CultureInfo)
        at System.Reflection.ClrType.InvokeMember(String, BindingFlags, Binder,

./System/Globalization/CultureInfo.cs
        at System.Globalization.CultureInfo..ctor(String)
        at Hello.Main()


2) When trying to create a neutral CultureInfo:
==================== hello.cs =======================
using System;
using System.Globalization;
class Hello {
  static void Main() {
    new CultureInfo("");
  }
}
=====================================================

$ cscc hello.cs -o hello.exe
$ ilrun hello.exe
Uncaught exception: System.NullReferenceException: The value 'null' was found 
where an instance of an object was required

./System/Globalization/CultureInfo.cs
        at System.Globalization.CultureInfo..ctor(String)
