首先，我对这类东西不是很熟练，所以我可能会写一些愚蠢的问题，请友善；-(
我有一个调用c++代码的R代码。不幸的是，我的代码有问题，可能是内存没有映射，我想用valgrind来了解错误在哪里。
我几年前就已经用过了，但现在似乎不起作用了。当我吃午饭时，以下命令
R -d valgrind
我得到这个输出

然后不加载R。我不知道该怎么解决。我知道错误"致命错误：无法创建'R_TempDir'"可能意味着硬盘上没有更多空间，但事实并非如此。
我在macbook pro上，有High Sierra和R 3.5.0
Valgrind生成一条错误消息，告诉您unix：475系统调用未被处理。
在这种情况下，它会向来宾应用程序报告系统调用失败，错误号为ENOSYS。
darwin上的系统调用475是mkdirat系统调用。我想当这个系统调用失败时，然后R报告无法创建R_Tempdir的致命错误。
如错误消息中所示，您应该提交一份关于valgrind-bugzilla的错误报告。
您也可以尝试解决这个问题：这可能是valgrind文件中的一个微不足道的更改m_syswrap/priv_syswrap-darwin.h，以制作类似于阅读上面几行的链接。
