The string component in the GNU C Library (aka glibc or libc6) through
2.28, when running on the x32 architecture, incorrectly attempts to use a
64-bit register for size_t in assembly codes, which can lead to a
segmentation fault or possibly unspecified other impact, as demonstrated by
a crash in __memmove_avx_unaligned_erms in
sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S during a memcpy.
