Question

某些C ++应用程序在OS X Snow Leopard中无缝编译和运行，但我最近更改为OS X Lion，在这里，尽管没有编译错误，但当我尝试运行它时，我收到错误＆＃34; Illegal说明：4＆＃34;，我不知道，可能是什么原因？

PS：

这些是我使用的链接标志

-Wl,-stack_size,0x10000000,-stack_addr,0xc0000000

这是我在sudo truss executable

时得到的输出

PS2：如果我删除前面提到的链接标志，程序就会运行，没有错误。但是当我向程序输入真实数据时，我得到了

Segmentation fault: 11

我记得这个程序有一个堆栈问题，所以必须增加它。在Linux中，我做了这个并且工作

       const rlim_t kStackSize = 256L * 1024L * 1024L;   // min stack size = 64 Mb
    struct rlimit rl;
    int result;

    result = getrlimit(RLIMIT_STACK, &rl);
    if (result == 0)
    {
            if (rl.rlim_cur < kStackSize)
            {
                    rl.rlim_cur = kStackSize;
                    result = setrlimit(RLIMIT_STACK, &rl);
                    if (result != 0)
                    {
                            fprintf(stderr, "setrlimit returned result = %d\n", result);
                    }
            }
    }

但是在OS X中，由于那不起作用，我使用了前面提到的链接标志，并且没有问题是OS X Snow Leopard，所以看起来我仍然有OS X Lion中的堆栈溢出问题但链接标志没有解决这个问题。我该怎么办？

Answer 1

我在Mountain Lion（10.8，）上构建产品然后在Lion上运行时遇到了这个问题。（10.7）。原因是我对构建环境进行了一些更改。

（我正在使用mkbundle发布使用Mono的产品。）

修复非常简单，我不得不告诉clang生成的二进制文件需要在OSX 10.6上运行。我在clang中添加了以下参数：

-mmacosx-version-min=10.6

问题解决了！

Answer 2

在OS X Lion（但也是10.5）中，堆栈大小硬限制为65532千字节（低于64 MiB）。这可以通过以下方式看出：

bswift$ ulimit -Hs
65532

即使是root用户，也无法增加此值。

软限制默认仅为8 MiB：

bswift$ ulimit -Ss
8192

在开始申请之前尝试将值提高到此最大值：

bswift$ ulimit -Ss unlimited
bswift$ ulimit -Ss
65532

注意：您观察到的segmentation fault (SIGSEGV)（编号11）是根据man setrlimit

超出堆栈限制时发送到进程的信号

注意：由于ulimit命令需要是内置的shell，因此您会在man bash

中找到它

Answer 3

这可能是permissions issue.

要进一步诊断，请在终端上以sudo dtruss为前缀运行程序。在抛出错误之前，请查看它运行的系统调用。

示例：sudo dtruss /path/to/application

您也可以使用Xcode或GDB调试器对其进行诊断。

“非法指令：4”出现在OS X Lion中
