Is it common for commercial airliners to nose-up when approaching stall conditions, thus making them easier to stall? (Or something else, that sounds similarly dire to a layman?)

I understand that aircraft are complex systems, and they need to be used by experts, and that those experts are aware of, and have to work to mitigate a lot of catastrophic failure scenarios. Is the unstable flight caused by the forward-mounted engines a particular example of a 'typical' quirk of a commercial airliner?
