GIS are particularly prone to these sort of human caused accidents. Example is that some GIS take coordinate input as LatLon and some take LonLat.
Another good example is that very often when working with GIS you collate data from multiple sources, as a sibling comment indicates. These sources may be available in all sorts of different coordinate systems and projections and it’s extremely easy to get bad results that are difficult to verify they are bad by these types of bugs.
