Flurry reports cxx_destruct related crash

I have a problem with an app crashing a few a times per day for a few users, I have no idea whats causing it and all I got is this stacktrace from flurry:

It looks like it's .cxx_destruct method is called multiple times and later somone tries to send a message to it? Why might the ViewControllers .cxx_destruct be called several times?

The class is contained within a UINavigationController which resides within a tabbar.

The ViewController's dealloc looks like this:

- (void)dealloc
{
    self.tableView.dataSource = nil;
    self.tableView.delegate = nil;
}

Arc is enabled.

I just faced the same Error like [SuperClassXY .cxx_destruct], but my code looks fine.

Then I found a few Breakpoints stacked directly on the @implementation line. (No idea where they come from)

Remove the Breakpoints and everything is fine.
