Reduced testcase:
void *g();

static void *count_and_verify_instructions(int *ninst,const unsigned char *p)
{
   if (p == ((void *)0))
    return g();
 *ninst = 0;
 return 0;
}
void f(int);
void *decode_window(const unsigned char *data)
{
  int ninst;
  void *svn_err__temp = count_and_verify_instructions(&ninst, data);
  if (svn_err__temp)
    return svn_err__temp;

  f (ninst);
  return 0;
}


So this is not a bug at all because g (svn_error_createf) could return null.
