... They won't be used in the eventual result, but 
just the fact that they are loaded from memory can mean that your program 
takes a SIGSEGV, for example, becaue it turns out "string" was just a 
single NUL byte at the end of a page, and there's nothing after it.

Funny.  I've seen this exact bug in memcmp and strcmp in earlier
SunOS (pre Solaris) libc when I was working on something like
Valgrind in my previous life.

Well, Valgrind actually can complain for no good reason.

To clarify, it was _not_ Valgrind I was mucking with.  And the
optimization used in the system library was wrong -- it stepped
over the page boundary without checking.  I found that it was
fixed in later releases (that was all before Sun started
calling their system Solaris).
