+ <div class="title">Half the Coverity issues in Gnash fixed in the next release</div>
+ <div class="date">29th April 2014</div>
+ <div class="body"><p>I've been following <a href="http://www.getgnash.org/">the Gnash
+project</a> for quite a while now. It is a free software
+implementation of Adobe Flash, both a standalone player and a browser
+plugin. Gnash implement support for the AVM1 format (and not the
+newer AVM2 format - see
+<a href="http://lightspark.github.io/">Lightspark</a> for that one),
+allowing several flash based sites to work. Thanks to the friendly
+developers at Youtube, it also work with Youtube videos, because the
+Javascript code at Youtube detect Gnash and serve a AVM1 player to
+those users. :) Would be great if someone found time to implement AVM2
+support, but it has not happened yet. If you install both Lightspark
+and Gnash, Lightspark will invoke Gnash if it find a AVM1 flash file,
+so you can get both handled as free software. Unfortunately,
+Lightspark so far only implement a small subset of AVM2, and many
+sites do not work yet.</p>
+
+<p>A few months ago, I started looking at
+<a href="http://scan.coverity.com/">Coverity</a>, the static source
+checker used to find heaps and heaps of bugs in free software (thanks
+to the donation of a scanning service to free software projects by the
+company developing this non-free code checker), and Gnash was one of
+the projects I decided to check out. Coverity is able to find lock
+errors, memory errors, dead code and more. A few days ago they even
+extended it to also be able to find the heartbleed bug in OpenSSL.
+There are heaps of checks being done on the instrumented code, and the
+amount of bogus warnings is quite low compared to the other static
+code checkers I have tested over the years.</p>
+
+<p>Since a few weeks ago, I've been working with the other Gnash
+developers squashing bugs discovered by Coverity. I was quite happy
+today when I checked the current status and saw that of the 777 issues
+detected so far, 374 are marked as fixed. This make me confident that
+the next Gnash release will be more stable and more dependable than
+the previous one. Most of the reported issues were and are in the
+test suite, but it also found a few in the rest of the code.</p>
+
+<p>If you want to help out, you find us on
+<a href="https://lists.gnu.org/mailman/listinfo/gnash-dev">the
+gnash-dev mailing list</a> and on
+<a href="irc://irc.freenode.net/#gnash">the #gnash channel on
+irc.freenode.net IRC server</a>.</p>
