+Summary: Error with gmcs and mcs  when specified bad ouput file
+
+Description of Problem:
+When compiling any file with mcs or gmcs and a incorrect specified ouput
+file is givin, the compiler get broken and throw a stacktrace
+
+Steps to reproduce the problem:
+1. Create a dummy file like this:
+dummy.cs:
+using System;
+
+class Test {
+        public static void Main(String[] args)
+        {
+                Console.WriteLine("dummy test");
+        }
+}
+
+2.Compile it with a bad ouput file like:
+
+mcs dummy.cs -out:/home/username or gmcs dummy.cs -out:/home/username
+
+if a directory is given instead of a file like the above example yo get this:
+
+albertein@cacharro:~/contanet/ContaNet$ gmcs dummy.cs -out:bin/
+
+Unhandled Exception: System.ArgumentException: name cannot be empty
+Parameter name: name
+in <0x0025a> System.Reflection.Emit.AssemblyBuilder:check_name_and_filename
+(string,string,bool)
+in <0x00021> System.Reflection.Emit.AssemblyBuilder:DefineDynamicModule
+(string,string,bool,bool)
+in <0x0001a> System.Reflection.Emit.AssemblyBuilder:DefineDynamicModule
+(string,string,bool)
+in <0x002a8> Mono.CSharp.CodeGen:Init (string,string,bool)
+in <0x00763> Mono.CSharp.Driver:MainDriver (string[])
+in <0x0001f> Mono.CSharp.Driver:Main (string[])
+
+there are not a difference if you use mcs or gmcs
+
+The compiler also get broken with you specified a output file where the
+current user don't have write permission, like:
+
+albertein@cacharro:~/contanet/ContaNet$ mcs dummy.cs -out:/etc/dummy.exe
+
+Unhandled Exception: System.UnauthorizedAccessException: Access to the path
+"/etc/dummy.exe" is denied.
+in <0x0055f> System.IO.FileStream:.ctor
+(string,System.IO.FileMode,System.IO.FileAccess,System.IO.FileShare,int,bool,bool)
+in <0x0005c> System.IO.FileStream:.ctor
+(string,System.IO.FileMode,System.IO.FileAccess)
+in <0x0003f> (wrapper remoting-invoke-with-check)
+System.IO.FileStream:.ctor (string,System.IO.FileMode,System.IO.FileAccess)
+in <0x0028a> System.Reflection.Emit.ModuleBuilder:Save ()
+in <0x004a7> System.Reflection.Emit.AssemblyBuilder:Save

+in <0x00017> System.Reflection.Emit.AssemblyBuilder:Save (string)
+in <0x00031> Mono.CSharp.CodeGen:Save (string)
+in <0x017db> Mono.CSharp.Driver:MainDriver (string[])
+in <0x0000f> Mono.CSharp.Driver:Main (string[])
+
+Once again, there aren't any difference if you use mcs or gmcs
+
+These were the cases that i could identify but i could be other ones.
+
+Actual Results:
+
+A stack trace
+
+Expected Results:
+
+A error message of the compiler, like Bad ouput file, or do you don;t have
+permission to write that output file
+
+How often does this happen? 
+
+always
+
+Additional Information:
+
+i'm using the mono 1.1.4 package
+
+albertein@cacharro:~/contanet/ContaNet$ mcs --version
+Mono C# compiler version 1.1.4.0
+
+maybe this is fixed in the svn vercion, if that is the case, i offer my
+apollogies for the innesesary alarm.
+
+This isn't a critical bug, but it's confusing and alarming that the
+compiler just get broken and throws a stacktrace instead of giving a nice
+and friendly user message.
