--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Another testcase, this time without -fsanitize=address:

void f(void) __attribute__((constructor));
void f(void)
{
    ;
}
int __RTL (startwith ("rtl-dfinit")) times_two (int i)
{
(function "times_two"
  (insn-chain
    (block 2
      (edge-from entry (flags "FALLTHRU"))
      (cnote 4 [bb 2] NOTE_INSN_BASIC_BLOCK)
      (edge-to exit (flags "FALLTHRU"))
    ) ;; block 2
  ) ;; insn-chain
) ;; function "times_two"
}
