我的一些 C++ 应用程序在 OS X Snow Leopard 中编译和运行都很顺利,但最近我改用了 OS X Lion,在这里,虽然没有编译错误,但当我尝试运行它时,出现了错误“非法指令:4”,我不知道原因是什么。
附注:
这些是我使用的链接标志
-Wl,-stack_size,0x10000000,-stack_addr,0xc0000000
当我执行sudo truss executable

PS2:如果我删除之前提到的链接标志,程序会运行而不出错。但是当我向程序输入真实数据时,就会出现
Segmentation fault: 11
我记得这个程序在使用堆栈时出现了问题,所以需要增加堆栈。在Linux上我进行了此操作并且成功了。
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中,由于那并不起作用,我使用了先前提到的链接标志,在OS X Snow Leopard中没有问题,所以看来我仍然在OS X Lion中遇到堆栈溢出问题,但链接标志无法解决这个问题。我该怎么办?
setrlimit(0x1003, 0xBFFFF8DC, 0x1) = -1 Err#22
显示setrlimit调用失败,并出现了EINVAL
“无效参数”(在/usr/include/sys/errno.h中查找的22)。虽然在输出顶部显示了失败的fprintf(...)错误消息,但由于在fprintf之后没有exit(1)
,因此程序将继续运行,而堆栈大小未被修改。 - Brian Swift
