mandelbug /man'del-buhg/ n.
 [from the Mandelbrot set] A
   bug whose underlying causes are so complex and obscure as to make
   its behavior appear chaotic or even non-deterministic.  This term
   implies that the speaker thinks it is a Bohr bug, rather than
   a heisenbug.  See also schroedinbug.
