That assuming the code was written that way initially. More often than not in long running projects pieces get moved around, refactored, functionality added and removed, and silent assumptions that were true before aren't true anymore. Somebody coded functionality for fixed data buffer, somebody else extended it with variable sized data but was not aware fixed buffers are being used, that stuff happens. We live in a myriad of glass castles, don't be so quick to throw stones around.
