Source file. Build with gmcs Main.cs

User-Agent:       Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.24 (KHTML,
like Gecko) Chrome/11.0.696.48 Safari/534.24

gmcs Main.cs gives a compiler crash. In the source, i accidentally invoke the
delegate definition rather then an instance of it. Please throw a nice
exception here.



Reproducible: Always

Steps to Reproduce:
1. compile source:
delegate string Test(string t);
        public static void Main (string[] args)
        {
            Test("t");
        }
2.
3.
Actual Results:  

error:
Internal compiler error at /tmp/test/test1/test1/Main.cs(9,36):: exception
caught while emitting MethodBuilder [MainClass::Main]
