This function is not marked to be inlined.  Therefore from my
perspective the compiler's behavior is incorrect because
the compiler is making an assumption as to what the memset() function
does.  The compiler is in effect subsitituting its own definition with
one provided by the run time library which is no longer being linked
to the application.
