我们使用ipnc_rdk 5.0版为TMS320DM365开发了一个应用程序。 我们在应用程序中有内存泄漏。 我们用arm-arago交叉编译valgrind for arm。 但是当我们在设备上运行valgrind时，它会显示非法的指令错误。
我们看到几个帖子告诉valgrind不支持armv5。 我们在下面的链接中获得了armv5的valgrind补丁，但它们无法应用于valgrind源代码。 https://bugs.kde.org/show_bug.cgi?id=248998 我们尝试为valgrind 3.9.0 3.8.1＆amp;添加补丁。 3.2.1版本
armv5有valgrind版本吗？ 如果不是，我们如何在我们的应用程序中调试内存泄漏错误。
此外，我运行顶级实用程序来检查内存使用情况，并且内存增加了。 kerenel也叫oom killer。请查找附加的日志，其中包含顶级实用程序输出以及内存不足日志
在调用oom killer之前的顶级实用程序输出：
