I've been very scared when accidentally used a shield while a different-purpose program is loaded in the arduino. Like PWM program on a display or using gsm library incompatible with a gsm module I am using. Can this also be an issue?

Yes I will add it ... if a sketch is putting 0V or 5V on a pin than several things can happen under the chapter Preventing wanted changes resulting in shortcuts

Can't tell if this was intentional, but I like the "two rules of Fight Club" approach to your advice about supplying 5V to 3.3V components.
