just add a javascript, then my project has a Internal compiler error.

I just add this javascript to my project and coding nothing in it, then my project has this error:

Internal compiler error. See the console log for more information. output was:
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object

  at Mono.CSharp.Driver.ParseArguments (System.String[] args, Boolean require_files) [0x00000] in <filename unknown>:0 

  at Mono.CSharp.Driver.Create (System.String[] args, Boolean require_files, Mono.CSharp.ReportPrinter printer) [0x00000] in <filename unknown>:0 

  at Mono.CSharp.Driver.Main (System.String[] args) [0x00000] in <filename unknown>:0 

Thanks for your help about this error.

I mean there is not exist my code.
sorry, this error log is base on C# file. whether C# or javascript file was added to my project, the mono.exe crush and the error is more or less the same.
And when I opened the example that unity3d owned, the same error appear!
