We are using a static code checker which is not
open-sourced (it is pretty good, though).  I am
not aware of any OpenSource static checker
capable of analyzing C++.

For runtime analysis we use (up to) three
different malloc libraries.  Each of them has
particular strengths and weaknesses.  Ah, yes --
sometimes the error's location and even the
error itself changes when linking against
different malloc lib.

All three work with C and C++ sources and are
GPLed.
