Track guessed as P from the FAILING STEP — line 1 of 7, ./compiler/pascal26 --threadsafe test/thread_glibc_malloc_two_threads.pas /tmp/test_tglibc226, which names test/thread_glibc_malloc_two_threads.pas. Not from the job's name or its src: those describe what the job is ABOUT, and this job's recipe spans 2 source file(s). The ranker reads frontmatter, so this line — not the body — decides who works it; correct it if the guess is wrong.

origin/master has advanced 2 commit(s) since this sha. Re-verify at current HEAD before acting — the callback is tagged to the sha that was tested, which may no longer be the state of the tree.

Range

The named sha b1f2b7d8812d CANNOT be the cause — it touches no buildable file (docs / tickets / tstate only). It is the sha that was TESTED, i.e. the upper bound of an untested range; the cause is somewhere below it.

bad b1f2b7d8812d, last good 9a245b91c409, 2 commit(s) in range — the watcher narrows this by idle bisect; check tstate/TSTATE.md for the current range.

Log

• 2026-09-28 — the borg watcher saw test-threads#src:test/thread_glibc_malloc_two_threads.pas@1 GREEN at 5c047cebce14 (tier native) and did NOT close this: the job's class is qemu, which testmgr treats as runtime-nondeterministic (RUN_RETRY_CLASSES) — a single pass does not refute a red there. The green is recorded because it is evidence and because a ticket that stops moving with no reason reads as forgotten; closing this one is a human's call.
• 2026-09-28 — frankD re-ran the failing step with the compiler whose sha256 is 0ded1e5d04c8 (built from master after the fix; the fix is on master): the --threadsafe compile of test/thread_glibc_malloc_two_threads.pas (step 1) exits 0, and the binary prints survived: both threads churned glibc malloc concurrently, rc 0. The failure was a compile-time refusal or a deterministic crash, so one run settles it; closed in the coordinator's sweep of tickets fixed on 2026-09-28.
• 2026-09-28 — resolved; this names the commit that carried the resolve, which is not always the one that carried the change — commit a3374ca262.
