Memory leaks valgrind向gtk init调用显示内存泄漏

我正在尝试检查代码中的内存泄漏，valgrind显示了许多错误。因为我以前从未使用过valgrind，所以我需要帮助。 首先，我专注于默认的gtk调用。 按照编码，内存从mkbib.c的140行泄漏。但是140号线正好

gtk_init(&argc, &argv);

我用过

G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind --tool=memcheck 
--leak-check=full --leak-resolution=high --num-callers=20 
--log-file=vgdump --suppressions=gtk.suppression ./mkbib

它与gtk.suppression一起取自

我发现一些讨论认为valgrind不适合检测gtk中的内存泄漏。这是我应该忽略的情况之一吗？或者我错过了什么

我所涉及的系统是：

gtk3-devel-3.6.4-1.fc18.x86_64

valgrind-3.8.1-9.fc18.x86_64

gcc（gcc）4.7.2 20121109

---

目前，您应该专注于代码中明确检测到的泄漏。Valgrind经常会在无法修改的外部组件上发现泄漏，甚至是商业库。您可以查阅有关忽略文件的文档，它们支持来自某些库的错误输出：

尝试将抑制文件修改为更通用的摘录示例：

...
obj:/usr/lib64/libgtk*（该问题似乎适用于任何gtk版本，包括gtk-2）
乐趣：g_选项\u上下文\u解析
乐趣：gtk_parse_args（或者可以使用“…”）
乐趣：gtk_init*（也适用于gtk_init_检查）

谢谢您的评论。但正如你所看到的，我使用了gtk本身所建议的抑制。但是那些泄漏仍然存在。我看了一下抑制文件，虽然我不是专家，但我认为你的错误不在其中。它没有包含正确库的行，尽管有包含正确函数的行，但在另一个库中。也许您可以生成另一个抑制文件，或者将所需的抑制添加到现有文件中。
