Q_ASSERT(res == local) in QDateTime::currentDateTime() on ios

I'm trying debug my ios app. I use QDateTime::currentDateTime() and get Q_ASSERT(res == local) which occur in QLocalTime func. I'm a little confused, how can res and locale be the same thing? Are two pointers being compared that cannot be equal, because the addresses are always different, or do I not understand something? The contents of these two pointers are absolutely identical.
