<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> my working assumption is that it's not actually sprintf but some private function inside MSVCRT's implementation of one of the sprintf-like functions. I did a pretty rigorous search of my leaked copies of the MSVCRT source (although the newest one I have to hand is 20 years old) and couldn't find anything that explains it, though. the constants don't match anything I would expect to see, either.</p>
