<p>This would only fix it for non-console GUI applications if I understand correctly. That's what we have here, but we'd still keep console applications buggy. There's no way to inject code before ExitProcess() with a plain console application.</p></div>
</blockquote>
<p>I was reading the ucrt source code yesterday and it does look like it processes atexit() registrations prior to ExitProcess(). So I'll go for that.</p></div>

<p>It does not work with <tt style="background: #ebebeb; font-size: 13px;">atext()</tt> -- I still get the same hang if I use that.</p>
<p>So:</p>
<ul class="remarkup-list">
<li class="remarkup-list-item"><tt style="background: #ebebeb; font-size: 13px;">std::atexit(...)</tt> -> hang</li>
<li class="remarkup-list-item"><tt style="background: #ebebeb; font-size: 13px;">qAddPostRoutine(...)</tt> -> no hang</li>
</ul>

<p>BTW, do you know if this problem happens with MinGW?</p></blockquote>
