Reduced testcase:
static const char *const multilib_exclusions_raw[] = {0};
struct obstack {
  char *next_free;
};
static struct obstack multilib_obstack;
int main (int argc, const char **argv)
{
  const char *p;
  const char *const *q;
  f();
  q = multilib_exclusions_raw;
  while ((p = *q++) != (char *) 0)
  {   
    int __len = (__builtin_strlen (p));
    __builtin_memcpy ((multilib_obstack.next_free), 0, (__len));    
  }
}
