Title:
  Weird test_meshfunc behavior

Status in Libpspio pseudopotential I/O library:
  New

Bug description:
  When I move tests around I get different values for the f1 and f1' and
  f1'' in test_meshfunc.

  Fragment from the diff:

     eid = pspio_meshfunc_set(&f1, m1, f, NULL, NULL);
     eid = pspio_error_flush();
  +  //
  +  DEBUG_PRINT("test_meshfunc: evaluating f1 at r=%f\n", r[6]);
  +  pspio_meshfunc_eval(f1, 1, &r[6], &feval);
  +  DEBUG_PRINT("test_meshfunc: result=%f\n", feval);
  +  DEBUG_PRINT("test_meshfunc: evaluating first derivative of f1 at r=%f\n", r[6]);
  +  pspio_meshfunc_eval_deriv(f1, 1, &r[6], &feval);
  +  DEBUG_PRINT("test_meshfunc: result=%f\n", feval);
  +  DEBUG_PRINT("test_meshfunc: evaluating second derivative of f1 at r=%f\n", r[6]);
  +  pspio_meshfunc_eval_deriv2(f1, 1, &r[6], &feval);
  +  DEBUG_PRINT("test_meshfunc: result=%f\n", feval);
  +  //

  
  Output:
  test_meshfunc: setting f1
  test_meshfunc: evaluating f1 at r=0.850000
  test_meshfunc: result=289.000000
  test_meshfunc: evaluating first derivative of f1 at r=0.850000

  test_meshfunc: evaluating second derivative of f1 at r=0.850000

  test_meshfunc: result=340.000000
  test_meshfunc: evaluating first derivative of f2 at r=0.850000
  test_meshfunc: result=340.000000
  test_meshfunc: evaluating second derivative of f1 at r=0.850000
  test_meshfunc: result=400.000000
  test_meshfunc: evaluating second derivative of f2 at r=0.850000
  test_meshfunc: result=400.000000

  
  Is it a bug or am I missing something?

  Attaching bzr diff.

  Thanks.
