NewFallback TC bug

[yoomee1313]

System information

Geth version: v1.9.21
OS & Version: OSX

Expected behaviour

• Fallback function of NewFallbacks solidity code fails due to out-of-gas.
• Since it fails, it should not get an event, and it should catch an error.

Actual behaviour

• It cannot catch the error.

Steps to reproduce the behaviour

tc location: accounts/abi/bind/bind_test.go
tc: NewFallback (line 1597 ~ line 1687)

-> bool gotEvent is set to true at point1, and it is not initialized. Then, fallback tx is failed, and event is not arrived.
-> At point2, the gotEvent is true even fallback tx is failed. So, it cannot catch the error.
-> If gotEvent = false code is inserted just before point3, it would catch an error.
-> Also, it would be nice if solidity code is fixed. calldatacopy(data, 0, calldatasize()) is not working. For me, below fallback function passes the NewFallback tc.

fallback() external {
    emit Fallback(data);
}

func TestNewFallbacks(t *testing.T) {

        // skip code...

	// Test receive function
	opts.Value = big.NewInt(100)
	c.Receive(opts)
	sim.Commit()

	var gotEvent bool
	iter, _ := c.FilterReceived(nil)
	defer iter.Close()
	for iter.Next() {
		// skip code...
		gotEvent = true //--------------------------------------------point1
		break
	}
	if !gotEvent {
		t.Fatal("Expect to receive event emitted by receive")
	}

	// Test fallback function
	opts.Value = nil // ------------------------------------------------point3
	calldata := []byte{0x01, 0x02, 0x03}
	fmt.Println("Fallback start")
	c.Fallback(opts, calldata)
	sim.Commit()

	iter2, _ := c.FilterFallback(nil)
	defer iter2.Close()
	for iter2.Next() {
		if !bytes.Equal(iter2.Event.Data, calldata) {
			t.Fatal("calldata mismatch")
		}
		gotEvent = true
		break
	}
	if !gotEvent {    //--------------------------------------------------point2
		t.Fatal("Expect to receive event emitted by fallback")
	}
}
