heisenbug
(encz) | heisenbug,heisenbergovská chyba n: [slang.] [tech.] Softwarová chyba,
která dočasně zmizí vždy, když je učiněn pokus o její nalezení (skutečně
se vyskytuje, protože nástroje pro hledání chyb zároveň ovlivňují
zkoumaný program) Jiří BlueBear Dluhoš |
heisenbug
(foldoc) | heisenbug
/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 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
corruption of the malloc arena) or errors that {smash the
stack}.
Opposite: Bohr bug. See also mandelbug, schroedinbug.

/hi:'zen·buhg/, n.
[from Heisenberg's Uncertainty Principle in quantum physics] A bug that
disappears or alters its behavior 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 uninitialized
memory, behaves quite differently.) Antonym of Bohr bug; see also {
mandelbug}, schroedinbug. In C, nine out of ten heisenbugs result from
uninitialized auto variables, fandango on core phenomena (esp. lossage
related to corruption of the malloc arena) or errors that {smash the
stack}.
