The libstdc++ library offers debugging versions of containers and iterators, much like the windows standard library. The windows library does periodically catch bugs for us, but typically as a breaking commit on MCI.

Since many developers work primarily against libstdc++, we should consider enabling its debugging features to try to catch similar errors sooner:

One restriction is that I think we can only do this when we are building against our vendored versions of C++ libraries, but that isn't too hard to enforce.
