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.

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.

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.
