During a time on the Google Docs team, the author discusses a challenging bug that caused crashes in the document editor. The bug was nondeterministic, making it difficult to reproduce consistently. After extensive debugging with a coworker and their Tech Lead, it was discovered that the issue stemmed from a refactoring error in V8 that affected Math.abs() function. The V8 team had already fixed the bug, so the Google Docs team added a temporary workaround for the specific Chrome version. The author reflects on the experience, highlighting the complexity of debugging and the importance of collaboration in finding solutions to technical issues.
