I'm glad I'm not the only one who has trouble when I hit this.

I really, really wish the STL had a mode you could compile it in which boiled down to, "Double check everything no matter how slow it makes things." Maybe it has it and I don't know it. But that was my top irritation with the little bit of C++ I've done.

I have no idea how a non-strict comparator can lead to memory corruption rather than just indeterminate sort order, but it is no fun tracking that down.
