• 2026-07-17: build failure fixed and published, pkgrel 1 -> 2. Confirmed the diagnosis from the 2026-07-07 note below is still accurate and root-caused it further: corral/semver/version/ compare_versions.pony’s _compare_pr_Fields match over (PreReleaseField, PreReleaseField) (PreReleaseField = U64 | String) already covers all four combinations in its four arms; the trailing else => Equal was added defensively (“should never get here but compiler complains without it”) for an older ponyc that didn’t do exhaustive tuple-pattern checking. Current ponyc does, and now treats that unreachable else as a hard error instead of a warning.
• Upstream already fixed this, just not in a tagged release yet: ponylang/corral commit 10b85e36e5c7ec4503ecb80ff51aa2342e459805 (“Switch all CI jobs to ponyc nightly (#300)”, merged 2026-03-12) removes exactly this else arm, plus retargets all CI workflows from ponyc:release to ponyc:nightly docker images/downloads (unrelated to the actual bug, just CI plumbing to catch this class of break earlier). No new pkgver exists yet – 0.9.2 (2019) is still the latest tag on GitHub.
• Fix: added that upstream commit’s .patch URL directly as a source=() entry (corral-0.9.2-unreachable-else.patch::https:// github.com/ponylang/corral/commit/10b85e36e5....patch), not a hand-authored local patch file – keeps provenance tied to the real upstream fix. Caveat: the full commit patch doesn’t apply cleanly with plain patch -Np1 against the 0.9.2 release tarball – 3 of the CI-workflow hunks fail (those files have drifted since 2019’s 0.9.2 tag; irrelevant to the build anyway). Worked around in prepare() with git init -q && git apply --include= 'corral/semver/version/compare_versions.pony' -p1 ... && rm -rf .git, which applies cleanly (git apply --include= scopes application to just the one file’s hunk, and can operate on a plain extracted-tarball directory once git init’d, no full repo needed). Packaging-only fix (source patch, not an upstream release), so pkgrel 1 -> 2 (plain integer bump is correct – this is maintained/, not adapted/, see memory/PKGREL_VS_PKGVER.md).
• Test-built clean with scripts/archlinuxaba-x86_64-build (0 compile errors; corral/corral-debug produced – namcap’s libatomic/glibc “missing depends” warnings are pre-existing/ unrelated to this fix, depends=() was already empty before this change, not addressed here). Signed and published to the private repo (x86_64). Note: publish had to be retried once after an unrelated transient SSH failure to the repo host (euroweb.lan) – no package-specific issue there.

Superseded (kept for context)

• Build failure during the 2026-07-07 “build all packages for x86_64” private-repo release pass. Fails compiling corral/semver/version/compare_versions.pony:32: match is exhaustive, the else clause is unreachable – a stricter modern ponyc now treats a redundant-but-harmless else arm as a hard compile error instead of a warning. Genuine source/toolchain-version incompatibility, not an environment setup issue like memory/corral-git.md’s CRT-object problem (same project, different failure). Not fixed as part of that pass.
