And I also verified on debian sid the selected memcpy/memmove is indeed the= one that optimized with glibc change (__memcpy_avx_unaligned_erms). I even trie= d to run glibc memcpy/memmove tests in this VM, where they stress a lot of diffe= rent sizes and alignments for different memcpy/memmove implementations. Also, my daily workstation (Ryzen 9 5900x) the uses a recent glibc that also contains this issue and I haven't see any memcpy/memmove related issue. So I am not sure if this is a glibc issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
