--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
What about this:

$ cat empty.c
int main()
{
  __builtin_malloc (12345);
  return 0;
}

$ gcc -fsanitize=leak empty.c && ./a.out 

=================================================================
==14721==ERROR: LeakSanitizer: detected memory leaks
