heisenbug
heisenbug /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.
They really exist! Already encountered them twice.
And I guess if Swarm wasn't designed this well we would have them
much more often.
