So you belived Microsoft and you thought XP is the most stable version of Windows out there? In fact it’s not. Zappadodle‘s people say this will break it:

main (){
  for (;;)
    printf ("Hung uptbbbbbb") ;

Well, I’ve not tried it, but I think it should not crash (at least, not with every compiler: it should depend on what microinstructions the compiler generates). If anyone could comment on this, please do so.
