Contributions summary:Fabrice contributed to the core OCaml system, specifically focusing on low-level runtime aspects. Their primary contribution involves adding a unique identifier to fibers, which required modifications to `runtime/fiber.c`, `runtime/caml/config.h`, and `runtime/caml/fiber.h`. Additionally, the user restored frame-pointers support for amd64 architecture, making changes to `runtime/amd64.S` and related files. These changes indicate a deep understanding of the OCaml runtime and low-level systems programming.
