Monkey patching is an (inelegant) option.
For example, suppose you don't like the fact that Flex 3 SpriteAsset.as returns a default border metrics of [7,7,7,7] (unlike flex 2). To fix this, you can:

Defence in depth is a good principle. But false security measures are a bad principle. The difference depends on a lot of details.

It's not necessarily that bad provided you know what context you're using it in.

I'll bet your STL uses a checked implementation for debug. This is probably a good thing, as it will catch iterator overruns and such. If it's that much of a problem for you, there may be a compiler switch to turn it off. Check your docs.
