I've once spent quite a few hours debugging a dangling pointer that wasn't zeroed after delete and was written to which might or might not have corrupted a piece of lua interpreter's state. fixing that felt good. the preceding 24 hours, not so much. |

Data races are particularly nasty because any print statements or debug tracing can trigger a memory fence/reorder and make the problem disappear.
Nothing more frustrating then adding a printf only to see the issue no longer manifest.
