--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase:
static void *j;
int v;
__attribute__((__leaf__)) int atoi (const char *);

int
main ()
{
  j =3D &&lab1;
  &&lab2;
  atoi ("42");
lab1:
lab2:
  if (v)
    goto *j;
}
which fails to link with -O2 starting with
r12-4240-g2b8453c401b699ed93c085d0413ab4b5030bcdb8
and with -O2 -ftree-vectorize starting with
r10-7522-g75efe9cb1f8938a713ce540dc3b27bc2afcd3fae=
