1I just mean to say that "heisenbug" is not a real "English word" as your question asks for, but more of a slang term used by programmers. – Patrick87 Sep 22 '15 at 15:52

Intermittent Error - An error that occurs sporadically, not consistently. It is the most difficult type of problem to diagnose and repair.

2I would say that an incomplete bug report by an end user is even more difficult to diagnose and repair :-) – Emil Vikström Sep 22 '15 at 15:22
