@item It will only trap non-conformant programs.  This means that fortify
  level 2 is treated in the same way as level 1.
@item Avoids making function calls when undefined behaviour has already been
  invoked.  This is handled by using @code{__builtin_trap()}.
@item Support for out-of-bounds read interfaces, such as @code{send()},
  @code{write()}, @code{fwrite()}, etc.
@item No ABI is enforced.  All of the fortify check functions are inlined
  into the resulting binary.
