When I compile on an ARM CPU, I see compiler warnings like this several times:

In file included from ../numpy/_core/src/common/simd/neon/neon.h:76,
                 from ../numpy/_core/src/common/simd/simd.h:85,
                 from ../numpy/_core/src/umath/loops_trigonometric.dispatch.c.src:9:
../numpy/_core/src/umath/loops_trigonometric.dispatch.c.src: In function ‘npyv_loadn_s32’:
../numpy/_core/src/common/simd/neon/memory.h:56:9: warning: ‘a’ is used uninitialized [-Wuninitialized]
   56 |     a = vld1q_lane_s32((const int32_t*)ptr,            a, 0);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I had just opened gh-25459 to fix that.
