Heisenbug         
In computer programming jargon, a heisenbug is a software bug that seems to disappear or alter its behavior when one attempts to study it. The term is a pun on the name of Werner Heisenberg, the physicist who first asserted the observer effect of quantum mechanics, which states that the act of observing a system inevitably alters its state.
heisenbug         
<jargon> /hi:'zen-buhg/ (From Heisenberg's Uncertainty Principle in quantum physics) A bug that disappears or alters its behaviour when one attempts to probe or isolate it. (This usage is not even particularly fanciful; the use of a debugger sometimes alters a program's operating environment significantly enough that buggy code, such as that which relies on the values of uninitialised memory, behaves quite differently.) In C, nine out of ten heisenbugs result from uninitialised auto variables, fandango on core phenomena (especially lossage related to corruption of the malloc arena) or errors that smash the stack. Opposite: Bohr bug. See also mandelbug, schroedinbug. [Jargon File] (1995-02-28)
Bohr bug         
<jargon, programming> /bohr buhg/ (From Quantum physics) A repeatable bug; one that manifests reliably under a possibly unknown but well-defined set of conditions. Compare heisenbug. See also mandelbug, schroedinbug. [Jargon File] (1995-02-28)
schroedinbug         
<jargon, programming> /shroh'din-buhg/ (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 harboured latent schroedinbugs for years. Compare heisenbug, Bohr bug, mandelbug. [Jargon File] (1995-02-28)
mandelbug         
<jargon, programming> /man'del-buhg/ (From the {Mandelbrot set}) A bug whose underlying causes are so complex and obscure as to make its behaviour appear chaotic or even nondeterministic. This term implies that the speaker thinks it is a Bohr bug, rather than a heisenbug. See also schroedinbug. [Jargon File] (1995-02-08)

Heisenbug

In computer programming jargon, a heisenbug is a software bug that seems to disappear or alter its behavior when one attempts to study it. The term is a pun on the name of Werner Heisenberg, the physicist who first asserted the observer effect of quantum mechanics, which states that the act of observing a system inevitably alters its state. In electronics, the traditional term is probe effect, where attaching a test probe to a device changes its behavior.

Similar terms, such as bohrbug, mandelbug, hindenbug, and schrödinbug (see the section on related terms) have been occasionally proposed for other kinds of unusual software bugs, sometimes in jest.
