<h2>概要</h2>
<p>プログラム開発時に有用な <a class="reference external" href="http://valgrind.org/">Valgrind</a> というツールがある。
Valgrindは色々なツールを提供してくれる。
この記事を書いた時点では以下のように書かれていて、6つのツールが提供されているとのこと。</p>
<blockquote>
The Valgrind distribution currently includes six production-quality tools: a memory error detector, two thread error detectors, a cache and branch-prediction profiler, a call-graph generating cache and branch-prediction profiler, and a heap profiler.</blockquote>
<p>今回はこの中でもメモリチェックツールのお話。
Linux上でpthreadを使用している場合に常にメモリリークとなってしまう件。</p>
<p>環境は以下。
Vagrantで作成したdebian sid。</p>
<div class="highlight"><pre><span></span>% uname -a

<div class="section" id="id3">
<h2>再現手順</h2>
<p>メモリリークしないコード <code>test.c</code> を用意する。
<code>pthread_create</code> して <code>pthread_join</code> するだけの簡単なお仕事。</p>

<p>スレッドとして起動する関数 <code>test</code> ではちょっと待ってから <code>pthread_exit</code> するだけ。
起動元では <code>pthread_join</code> してあげる。
これでスレッド用の資源が回収されるのでメモリリークはない。はずなのだが・・・。</p>
<p>このプログラムをコンパイルして、valgrindを実行してみる。</p>
