Hi Zdenek,

Could you please double check the strncpy implementation on your side? and help
to file one glibc issue if so.

One further reduced test case:

#define N 3
char a[N];
char c[N];

int
main (void)
{
  asm volatile("xxspltib 18, 0xf" : : :"vs18");
  __builtin_strncpy (c, a, N);
  if (c[0] || c[1])
    __builtin_abort ();
  return 0;
}
