<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Might make sense to move the declaration and initialization down to within the conditional, so that the code mirrors the other places within this source file.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I sometimes switch between running asterisk as user and root. When refcounting is enabled, asterisk crashes when trying to fprintf to a NULL FILE* when it cannot fopen /tmp/refs.
I didn't go for fancy error checking and warnings: just checking for writability is fine for my purposes. The refcounting user should be smart enough to check for file permissions when the file stays empty.
(Second diff removes a red blob.)</pre>
