> **Our Zig codebase had one leak and one undefined memory access.** That was _really surprising to me_ (in a good way). Our Zig codebase is large, complex, and uses tons of memory tricks for performance that could easily lead to unsafe behaviors. I thought we’d have a lot more issues, honestly. Also, the one leak found was during calling a 3rd party C API (so Zig couldn’t detect it). So this is a huge success.
