A Schroedinbug is an issue that happens in a computer program where the program does something unexpected because it was not programmed to expect certain kinds of input or information. For example, if someone puts in their age as "eleventy billion," a program without a Schroedinbug would not know what to do – it wouldn't know how to process such a large number. But with a Schroedinbug, the program may do something silly, like say that the person is 900 years old! Basically, a Schroedinbug is an issue in a computer program that makes it do something it wasn't programmed to do.
