Whose bug is this anyway?
<i>"The bug was easily fixed by upgrading the build server, but in the end we decided to leave assertions enabled even for live builds. The anticipated cost-savings in CPU utilization (or more correctly, the anticipated savings from being able to purchase fewer computers in the future) were lost due to the programming effort required to identify the bug, so we felt it better to avoid similar issues in future."</i><p>I'd like to ask: for anyone here who's ever worked on a large C++ codebase, were assertions ever actually observed to be a noticeable detriment to performance? I'm sort of naively assuming that a good branch predictor would make their impact negligible, but I ain't exactly a system programmer.
