问HN：你在2025年追踪到的最棘手的bug是什么？
我们常常讨论功能发布，但我想听听那些艰难的经历。<p>我花了将近一个月的时间追踪一个无声的数据损坏问题，结果发现是x86和ARM芯片之间的浮点非确定性。这彻底改变了我对“可靠”内存的看法。<p>你今年的“白鲸”bug是什么？

We talk a lot about shipping features, but I want to hear the war stories.<p>I spent almost a month chasing a silent data corruption issue that turned out to be floating-point non-determinism between x86 and ARM chips. It completely changed how I look at "reliable" memory.<p>What was your "white whale" bug of the year?
