--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r256580.  Got fixed or went latent with r265677 on the trunk.

Reduced testcase with -m32 -dA -g -O2 -fpie -fvisibility=hidden:
void
foo (char *b)
{
  unsigned c = 0;
  --c;
  do
    if (++*b++ == 0)
      break;
  while (--c);
  if (c == 0)
    while (*b++)
      ;
}

void
bar (void)
{
  foo ("");
}
