Examples

“I recently encountered a particularly infuriating Heisenbug. A large program⟳, when given a large input, was just mysteriously dying. Of course, I ran it under the debugger. The mystery deepened: the program⟳ returned quietly to the debugger.”

“Except for pointer messups in C on my side, the Heisenbugs I've come⟳ across were hardly ever caused by _me_.”

“There are multiple perf related issues like⟳ this that are hard to track down. They are borderline heisenbugs that are possibly race⟳ conditions, so bisecting doesn't work⟳ and even things like⟳ enablibg^([sic]) ftrace will make⟳ the issue⟳ go away (or crash⟳ ftrace itself).”
