By the way, for those who are interested, some Berkeley researchers
presented a "taint checker" for C++ at CodeCon.  (It's actually a
general-purpose parser that tracks "data flow" statically, i.e.
in source code.  Pretty amazing, considering that it can handle
templates properly.)  They ran the Linux kernel through it and
found six unnoticed security bugs(!)
