Wow, thanks! I've been looking at the 5.8.1 version of perlxs, which doesn't mention the automatic mortalization of RETVAL at all. It looks like that section was added in 5.8.4.
(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?)
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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
