Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

I've been running the libc++ tests off and on for a while. It's a quite extensive test suite, but I wondered if there were any bugs that the test suite was not uncovering. In the upcoming clang 3.3, there is a new feature named Address Sanitizer which inserts a bunch of runtime checks into your executable to see if there are any "out of bounds" reads and writes to memory.
In the back of my head, I've always thought that it would be nice to be able to say that libc++ was "ASan clean" (i.e, passed all of the test suite when running with Address Sanitizer).
So I decided to do that.
