  Yes, that does look fairly complete, except for the issues I outlined.  As 
  far as I know, Yasm does not support the mandatory function markup required 
  by Windows x86-64, and as such the DLLs produced this way are invalid 
  executables.  If an exception were to occur in one of those assembly 
  language routines, even one that is automatically recovered by ntdll.dll, 
  the process will be terminated without an error message.  (This is because 
  ntdll.dll assumes that an exploit has occurred, and the complex procedure to 
  display a message box stands a good chance of executing shellcode if memory 
  has been corrupted.)
Wow, this is a sophisticated operating system, suppressing the error
message indeed!

I don't know much about Windos, but I suppose such advanced protection
mechanism has resulted in an almost flawless track record wrt security
