+Summary: SOAP: fooSpecified return arguments crash on NullRef
+
+Description of Problem:
+A simple scenario involving the usage of fooSpecified return argument for
+optional XML attributes crashes with a NullReferenceException.
+
+Steps to reproduce the problem:
+1. Make the following XML file available under http://127.0.0.1:5555/, e.g.
+using:
+
+         (printf "HTTP/1.1 200 OK\\r\\nContent-Type: text/xml\\r\\n"; \
+                printf "Content-Length: $(cat "soap-response.xml"|wc
+-c)\\r\\n\\r\\n";cat "soap-response.xml") | \
+                nc -l -p 5555 >/dev/zero 2>&1 &
+
+
+<soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>
+ <soap:Body>
+  <Resp xmlns="urn:foo"/>
+ </soap:Body>
+</soap:Envelope>
+
+
+2. Invoke the following code:
+    //using System.Diagnostics;
+    using System.Web.Services;
+    //using System.ComponentModel;
+    //using System.Web.Services.Protocols;
+    using System;
+    using System.Xml.Serialization;
+
+    [System.Web.Services.WebServiceBindingAttribute(Name="Foo",
+Namespace="urn:foo")]
+    public partial class FooService :
+System.Web.Services.Protocols.SoapHttpClientProtocol {
+        static void Main() {
+            FooService service = new FooService();
+            service.Url = "http://127.0.0.1:5555";
+            int a;
+            bool b;
+            service.Req("x", out a, out b);
+            Console.WriteLine(b);
+        }
+
+        public FooService() {
+            this.SoapVersion =
+System.Web.Services.Protocols.SoapProtocolVersion.Soap12;
+        }
+
+        [System.Web.Services.Protocols.SoapDocumentMethodAttribute("",
+RequestElementName="Req", RequestNamespace="urn:foo",
+ResponseNamespace="urn:foo",
+Use=System.Web.Services.Description.SoapBindingUse.Literal,
+ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
+        [return: System.Xml.Serialization.XmlElementAttribute("Hits")]
+        public Elem[]
+Req([System.Xml.Serialization.XmlAttributeAttribute()] string arg,
+[System.Xml.Serialization.XmlAttributeAttribute()] out int status,
+[System.Xml.Serialization.XmlAttributeAttribute()]
+[System.Xml.Serialization.XmlIgnoreAttribute()] out bool statusSpecified) {
+            object[] results = this.Invoke("Req", new object[] {
+                        arg});
+            status = ((int)(results[1]));
+            statusSpecified = ((bool)(results[2]));
+            return ((Elem[])(results[0]));
+        }
+    }
+
+    [System.SerializableAttribute()]
+    public partial class Elem {
+        private string attrField;
+
+        [System.Xml.Serialization.XmlAttributeAttribute()]
+        public string attr {
+            get {
+                return this.attrField;
+            }
+            set {
+                this.attrField = value;
+            }
+        }
+    }
+
+Actual Results:
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+  at FooService.Req (System.String arg, System.Int32& status,
+System.Boolean& statusSpecified) [0x00000]
+  at (wrapper remoting-invoke-with-check) FooService:Req (string,int&,bool&)
+  at FooService.Main () [0x00000]
+
+Expected Results:
+"False" on the console.
+Minimalistic expected result: NotSupportedException.
+
+How often does this happen?
