Article: 20 months tracking down an elusive bug in code
« on: February 27, 2018, 12:44 AM »
Nice article on tracking down an elusive unpredictable problem that was related to an operating system bug.

Flaky failures are the worst. In this particular investigation, which spanned twenty months, we suspected hardware failure, compiler bugs, linker bugs, and other possibilities. Jumping too quickly to blaming hardware or build tools is a classic mistake, but in this case the mistake was that we weren’t thinking big enough. Yes, there was a linker bug, but we were also lucky enough to have hit a Windows kernel bug which is triggered by linkers!
