Question

我有一个巨大的二进制文件，文本部分大约需要876MB。我想检查内存泄漏。当我使用valgrind命令 valgrind --leak-check=yes /path/to/binary args 它给了我以下输出和退出。我是新手，不知道如何进一步解释这一点。有没有办法让valgrind使用我的二进制文件。

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

您尚未指出正在使用的valgrind版本。但是最近的valgrind版本已经改变了这样一个失败的断言 a＆＃39;抱怨一次＆＃39;警告。

因此，您应该升级到最新版本并重试。

Valgrind退出而没有给出任何输出
