[SOLVED] EXC_BAD_ACCESS crash when creating Actions

cocos2d-x C++

I am creating a series of 6 actions to flash a node (a large button), however it’s crashing with EXC_BAD_ACCESS (code=2):

at this line:

void Ref::retain()
{
    CCASSERT(_referenceCount > 0, "reference count should be greater than 0");
    ++_referenceCount;                  // <--- HERE
}

Here is the code I am using:

void GameScene::flashButtons()
{
	_leftButton->runAction(createButtonFlashAction());
	_rightButton->runAction(createButtonFlashAction());
}

Action *GameScene::createButtonFlashAction()
{
	return Sequence::create(
		FadeIn::create(0.5f),
		FadeOut::create(0.5f),
		FadeIn::create(0.5f),
		FadeOut::create(0.5f),
		FadeIn::create(0.5f),
		FadeOut::create(0.5f)
		);
}

I am using Cocos2d-x v3 (github version; updated today). What am I doing wrong? It looks like the memory has been deallocated already?

Any help would be appreciated.

Oops, I should have waited a few minutes. The compiler (Xcode) told me what the issue was; I am missing the terminating nullptr sentinel from that list of actions… problem solved.
