+Summary: NullReferenceException at System.Reflection.Emit.ModuleBuilder.Save() on Windows
+
+Description of Problem:
+On Windows, System.Reflection.Emit.ModuleBuilder.Save() results in
+NullReferenceException like:
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+in <0x76bcca79> (wrapper managed-to-native)
+System.Reflection.Emit.ModuleBuilder:WriteToFile (intptr)
+in <0x00004> (wrapper managed-to-native)
+System.Reflection.Emit.ModuleBuilder:WriteToFile (intptr)
+in <0x00283> System.Reflection.Emit.ModuleBuilder:Save ()
+in <0x004d0> System.Reflection.Emit.AssemblyBuilder:Save
+(string,System.Reflection.PortableExecutableKind,System.Reflection.ImageFileMachine)
+in <0x00014> System.Reflection.Emit.AssemblyBuilder:Save (string)
+in <0x00032> Mono.CSharp.CodeGen:Save (string)
+in <0x016d2> Mono.CSharp.Driver:MainDriver (string[])
+in <0x0000f> Mono.CSharp.Driver:Main (string[])
+
+
+Steps to reproduce the problem:
+Compile any C# sources that the resulting assembly should be successfully
+generated.
+
+public class Test { public static void Main () {}; }
+
+Actual Results:
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+in <0x76bcca79> (wrapper managed-to-native)
+System.Reflection.Emit.ModuleBuilder:WriteToFile (intptr)
+in <0x00004> (wrapper managed-to-native)
+System.Reflection.Emit.ModuleBuilder:WriteToFile (intptr)
+in <0x00283> System.Reflection.Emit.ModuleBuilder:Save ()
+in <0x004d0> System.Reflection.Emit.AssemblyBuilder:Save
+(string,System.Reflection.PortableExecutableKind,System.Reflection.ImageFileMachine)
+in <0x00014> System.Reflection.Emit.AssemblyBuilder:Save (string)
+in <0x00032> Mono.CSharp.CodeGen:Save (string)
+in <0x016d2> Mono.CSharp.Driver:MainDriver (string[])
+in <0x0000f> Mono.CSharp.Driver:Main (string[])
+
+
+Expected Results:
+Should be built.
+
+How often does this happen? 
+always.
+
+Additional Information:
+It happens since r36094. r36092 works fine.
+
+Am using the latest mingw runtime (3.5-1).
