Can you give an example?
I'm asking because we take into account a bunch of error sources that we collectively refer to as "altimeter error" and budget for that in air traffic management. That is for example why we separate aircraft vertically by a certain minimum amount, which may be dependent on what kind of instruments you have, and why we have minimum altitudes and mix/max temperatures and such.
I am aware of accidents that have happened because the altimeter was set to the wrong datum, or because it was misread by the pilot (a notoriously easy mistake to make with old school mechanical stuff) but I never heard of an incident caused by unmitigated system errors.
