Typo: "GM" → "GB".

The TCONF handling is correct. Note that `tst_brk()` is `__attribute__((noreturn))`, so the `break` is unreachable. It's still fine to add for static-analysis tools and readability, but the commit message calling it a "missing" break is a stretch — it was never functionally absent.

**Verdict: Needs revision** — fix the "GM" → "GB" typo in the commit body. The code change itself is correct.
