Although in slightly different vein and, strictly speaking, not reported to a public bug tracker, this AMD CPU bug report by Matt Dillon is probably my favourite (link: https://www.dragonflybsd.org/mailarchive/kernel/2012-03/msg0...). Tracking the intermittent problem to the lowest level and blaming the CPU and not the numerous layers above it surely takes guts.
You can say what you want about Drepper, but as far as scanf() and siblings are concerned, there is only one one safe way of using them: Not using them. Better write comprehensible reliable code to implement input scanning.
