Schroedinbug is a term used in software programming to describe a computer bug that is not discovered, but shows up after somebody reads the source or uses the application in an unusual way. The program then stops working for everyone until the bug is fixed. Although this sounds rather impossible, some programs have carried latent schroedinbugs.
Etymology
The word schroedinbug comes from Schrödinger's cat thought experiment.
