Cython statistics library (t-digest, summary stats) with a numpy build-time dependency. Backports two small upstream fixes (sequence point, type-punning) that landed on main after the 0.0.8 tag but before any release.
Neither cp314 nor cp314t is upstream-supported (tests.yml stops at 3.13, no free-threaded env or classifiers); cp314 segfaults building a crick object during test collection and cp314t's test_object_reference_counting fails because free-threaded CPython's immortal objects break sys.getrefcount() arithmetic -- both unrelated to riscv64. Also fix the wheel-contents check: the licenses/ directory entry itself matched the .dist-info/licenses/ glob and rsplit to an empty string.

crick0.0.8Compiles crick's t-digest, space-saving, and summary-stats Cython extensions against numpy's C API into a wheel. Upstream publishes no riscv64 wheel.

Matrix: cp310-cp313, no cp314/cp314t - upstream's own CI (and
requires-python) covers only 3.10-3.13; cp314 segfaults building a crick object during test collection and cp314t'stest_object_reference_countingfails because free-threaded CPython's immortal objects break plainsys.getrefcount()arithmetic, both unrelated to riscv64.Testing
CIBW_TEST_REQUIRES- crick doesn't declare it as a runtime dependency even though the compiled extensions call numpy's C API at import time.License: OK
Patches
0001-Fix-sequence-point-error-in-stats_kurt.patch- Backport dask/crick@720de70c. Redundant self-assignment flagged as undefined behaviour by strict compilers; reproduces off riscv64 too.0002-Avoid-dereferencing-a-type-punned-pointer-in-asint64.patch- Backport dask/crick@70d9dc24. Strict-aliasing violation that can miscompile under -O2/-O3; reproduces off riscv64 too. Both landed on upstreammainafter the0.0.8tag; no release contains them yet.Built on cp312; 69 passed, 30 skipped.
