Reported by <gnulib@mifar.in> in <https://lists.gnu.org/archive/html/bug-gnulib/2026-09/msg00097.html>. * m4/aligned_alloc.m4 (gl_FUNC_ALIGNED_ALLOC_WORKS): New macro, extracted from gl_FUNC_ALIGNED_ALLOC. (gl_FUNC_ALIGNED_ALLOC): Use it. * m4/alignalloc.m4 (gl_ALIGNALLOC): Invoke gl_FUNC_ALIGNED_ALLOC_WORKS and define HAVE_WORKING_ALIGNED_ALLOC. * lib/alignalloc.h (ALIGNALLOC_VIA_ALIGNED_ALLOC): Test HAVE_WORKING_ALIGNED_ALLOC, instead of testing for an address sanitizer. * modules/alignalloc (Files): Add m4/aligned_alloc.m4.
