+Summary: mcs crashes when it doesn't have permission to write to output file.
+
+Description of Problem:
+mcs crashes when it doesn't have permission to write to output file.
+
+Steps to reproduce the problem:
+1. Create a C# program file hello.cs (It can do anything -- that's not
+important)
+
+2. Run these commands to revoke write permission to hello.exe, and then
+compile hello.cs file
+$ >hello.exe
+$ chmod 0 hello.exe
+$ mcs hello.cs
+
+
+Actual Results:
+
+Unhandled Exception: System.UnauthorizedAccessException: Access to the path
+"./hello.exe" is denied.
+in <0x00428> System.IO.FileStream:.ctor
+(string,System.IO.FileMode,System.IO.FileAccess,System.IO.FileShare,int,bool)
+in <0x0005e> System.IO.FileStream:.ctor
+(string,System.IO.FileMode,System.IO.FileAccess)
+in <0x00077> (wrapper remoting-invoke-with-check)
+System.IO.FileStream:.ctor (string,System.IO.FileMode,System.IO.FileAccess)
+in <0x00302> System.Reflection.Emit.ModuleBuilder:Save ()
+in <0x005c8> System.Reflection.Emit.AssemblyBuilder:Save
+(string,System.Reflection.PortableExecutableKind,System.Reflection.ImageFileMachine)
+in <0x00017> System.Reflection.Emit.AssemblyBuilder:Save (string)
+in <0x00035> Mono.CSharp.CodeGen:Save (string)
+in <0x018e1> Mono.CSharp.Driver:MainDriver (string[])
+in <0x0000f> Mono.CSharp.Driver:Main (string[])
+
+Expected Results:
+It should handle the exception and report an error message
+
+How often does this happen? 
+Always
+
+Additional Information:
+The same kind of behaviour is exhibited when the output directory does not
+have write permission.  For instance, try the following:
+
+$ chmod -w .
+$ mcs hello.cs
+
+This compilation also crashes (the same exception specified earlier).
