"非法指令:4"出现在OS X Lion中

Question

一些C++应用程序编译和OS X Snow Leopard中无缝运行,但我最近改为OS X Lion中,在这里,虽然没有编译错误,当我尝试运行它,我得到的错误"非法指令:4",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 

这是我得到的输出 sudo truss executable

PS2:如果我删除前面提到的链接标志,程序运行,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.在Linux中我做到了这一点并且有效

       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);
                    }
            }
    }

但在OS X,因为没有工作,我用前面提到的链接标志,并没有问题,是OS X雪豹,这样看来我还是有OS X Lion中的堆栈溢出的问题,但链接标志不解决这个.我能做什么？

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(仅低于64 MiB).这可以看作:

bswift$ ulimit -Hs
65532

即使是root,我也无法增加这个价值.

软限制默认仅为8 MiB:

bswift$ ulimit -Ss
8192

尝试在开始应用程序之前将值提高到此最大值:

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

注意:segmentation fault (SIGSEGV)您观察到的(编号11)是根据超出堆栈限制时发送到进程的信号man setrlimit

注意:由于ulimit命令需要是内置的shell,因此您将在文档中找到它man bash
