Show HN: Fixing a single pointer bug unlocked 1M+ row JSON parsing on Windowshttps://news.ycombinator.com/item?id=45979409I've been building a cross-platform JSONL viewer app that handles multi-GB files. It worked perfectly on macOS (my development machine), but consistently crashed on Windows at exactly 2,650 KB. Here's the debugging journey and the tiny fix that made all the difference.The Problem- macOS: Handles 5GB+ files effortlessly - Windows: Crashes at 2,650 KB every time - Same codebase, cross-compiled from Mac Silicon to Windows using MinGWThe InvestigationAdded detailed logging to track execution. The crash happened during string interning after successfully parsing ~6,000 rows. Not during parsing, not during file I/O, but during the merge phase.The Root CauseMy StringPool class used std::unordered_map to deduplicate strings. The string_views pointed into a std::vector.When the vector grew and reallocated, all the string_view keys became dangling pointers. The hash map was full of invalid references.Why did it work on macOS? Different memory allocator behavior, different default stack sizes (8MNov 19, 2025 1:43 PM

This feature, recognized by its sharp decline in cosmic ray numbers above 3 PeV, has puzzled researchers for nearly 70 years. Recent studies published in National Science Review and Science Bulletin reveal that micro-quasars powered by black hoNov 17, 2025 11:22 PM
