TST: Fix test that uses unininitialized memory (#29232)

)* MAINT: Update download-wheels for multiple pagesThe anaconda staging repositories have changed layout and now only25 files are showing per page. This update uses a different URL tograb all of the names, thus avoiding the need for paging.There are also some cleanups and added comments to make futuremaintenance easier.[skip azp] [skip cirrus] [skip actions]* ENH: Disable the alloc cache under address and memory sanitizersWe've been carrying a variant of this patch in our local copy of NumPyfor some time. The alloc cache reduces the effectiveness ofuse-after-free or use-of-uninitialized memory warnings because cachingof allocations means they may be reused for a different allocation,potentially hiding real problems.* ENH, SIMD: Initial implementation of Highway wrapperA thin wrapper over Google's Highway SIMD library to simplify its interface.This commit provides the implementation of that wrapper, consisting of:- simd.hpp: Main header defining the SIMD namespaces and configuration- simd.inc.hpp: Template header included multiple times with different namespacesThe wrapper eliminates Highway's class tags by:- Using lane types directly which can be deduced from arguments- Leveraging namespaces (np::simd and np::simd128) for different register widthsA README is included to guide usage and document design decisions.* SIMD: Update wrapper with improved docs and type support  - Fix hardware/platform terminology in documentation for clarity  - Add support for long double in template specializations  - Add kMaxLanes constant to expose maximum vector width information  - Follows clang formatting style for consistency with NumPy codebase.* SIMD: Improve isolation and constexpr handling in wrapper  - Add anonymous namespace around implementation to ensure each    translation unit gets its own constants based on local flags  - Use HWY_LANES_CONSTEXPR for Lanes function to ensure proper    constexpr evaluation across platforms* Update Highway submodule to latest master* SIMD: Fix compile error by using MaxLanes instead of Lanes for array size  Replace hn::Lanes(f64) with hn::MaxLanes(f64) when defining the index array  size to fix error C2131: "expression did not evaluate to a constant". This error  occurs because Lanes() isn't always constexpr compatible, especially with  scalable vector extensions. MaxLanes() provides a compile-time constant value  suitable for static array allocation and should be used with non-scalable SIMD  extensions when defining fixed-size arrays.* SIMD: Rename NPY_SIMDX to NPY_HWYRename Highway wrapper macros for clarity:- NPY_SIMDX → NPY_HWY- NPY_SIMDX_F16 → NPY_HWY_F16- NPY_SIMDX_F64 → NPY_HWY_F64- NPY_SIMDX_FMA → NPY_HWY_FMATo avoids confusion with legacy SIMD macros.* Disable Highway EMU128 scalar emulationSkip Highway's EMU128 in favor of NumPy's scalar implementations fordue to strict IEEE 754 floating-point compliance requirements* TYP: Type ``MaskedArray.__{iadd,isub,imul,itruediv,ifloordiv,ipow}__`` (numpy#28986)* MNT: fix linter issues on main* MNT: switch back to setup-python in CI* CI: update cibuildwheel to 3.0.0b1 and enable cp314 [wheel build]* MNT: respond to code review [wheel build]* MNT: move back to 'cd tools' hack [wheel build]* DOC: Fixes line numbers on classes decorated with set_module (numpy#28629) (numpy#28918)* MAINT: Bump larsoner/circleci-artifacts-redirector-actionBumps [larsoner/circleci-artifacts-redirector-action](https://github.com/larsoner/circleci-artifacts-redirector-action) from 1.0.0 to 1.1.0.- [Release notes](https://github.com/larsoner/circleci-artifacts-redirector-action/releases)- [Commits](scientific-python/circleci-artifacts-redirector-action@4e13a10...7eafdb6)---updated-dependencies:- dependency-name: larsoner/circleci-artifacts-redirector-action  dependency-version: 1.1.0  dependency-type: direct:production  update-type: version-update:semver-minor...Signed-off-by: dependabot[bot] <support@github.com>* BEG, MAINT: Begin NumPy 2.4.0 development.- Create 2.4.0-notes.rst- Update release.rst- Update pavement.py- Update pyproject.toml- Update cversions.txt- Update numpyconfig.h- Delete release fragments* Fix workflow error* BUG: Avoid compile errors in f2py modulesSome of the casts from cfuncs pass PyObject* to PyArrayObject*, whichcauses compile errors due to incompatible pointer types on at leastGCC 14.* DOC: Expand/clean up extension module import errorWe get a lot of these reports and it is never us...

discussionnumpy#29179 (numpy#29188)* TYP: Support iteration of ``StringDType`` arrays* BUG: Address interaction between SME and FPSR (numpy#29223)* BUG: Address interaction between SME and FPSRThis is intended toresolvenumpy#28687The root cause is an interaction between Arm Scalable Matrix Extension (SME) and the floating point status register (FPSR). As noted in Arm docs for FPSR, "On entry to or exit from Streaming SVE mode, FPSR.{IOC, DZC, OFC, UFC, IXC, IDC, QC} are set to 1 and the remaining bits are set to 0".  This means that floating point status flags are all raised when SME is used, regardless of values or operations performed.These are manifesting now because Apple Silicon M4 supports SME and macOS 15.4 enables SME codepaths for Accelerate BLAS / LAPACK.  However, SME / FPSR behavior is not specific to Apple Silicon M4 and will occur on non-Apple chips using SME as well.Changes add compile and runtime checks to determine whether BLAS / LAPACK might use SME (macOS / Accelerate only at the moment).  If so, special handling of floating-point error (FPE) is added, which includes:- clearing FPE after some BLAS calls- short-circuiting FPE read after some BLAS callsAll tests passPerformance is similarAnother approach would have been to wrap all BLAS / LAPACK calls with save / restore FPE.  However, it added a lot of overhead for the inner loops that utilize BLAS / LAPACK.
