schroedinbug /shroh'din-buhg/ n.

[MIT: from the
Schroedinger's Cat thought-experiment in quantum physics] A design
or implementation bug in a program that doesn't manifest until
someone reading source or using the program in an unusual way
notices that it never should have worked, at which point the
program promptly stops working for everybody until fixed. Though
(like bit rot) this sounds impossible, it happens; some
programs have harbored latent schroedinbugs for years. Compare
heisenbug, Bohr bug, mandelbug
