<p>Wow, thanks! I've been looking at the 5.8.1 version of [doc://perlxs], which doesn't mention the automatic mortalization of RETVAL at all. It looks like that section was added in 5.8.4.</p>
<p>(Inline was written quite a while before this feature was documented, so maybe ingy didn't know about it and that's why the Inline::C documentation doesn't mention it?)</p>
<p>You'd think that not knowing about this would have caused me problems by now. The odd thing is, I've just looked over all my XS code and I don't seem to have run afoul of it anywhere. I suppose it helps that I usually use PPCODE instead of CODE.</p>
