Eclipse 为 g++ 不返回的代码返回错误

Question

构建简单代码（示例如下）在 eclipse 上返回错误，而命令行中的 g++ 不会。 eclipse 和 g++ 输出的可执行文件都执行相同的操作（结果符合我的预期）。当代码不像我展示的示例那样简单时，这很痛苦。任何想法都值得赞赏。

环境：Eclipse Indigo CDT，Ubuntu 10.10

示例代码：

//For test_boostStr()
#include <boost/algorithm/string.hpp>
#include <vector>
#include <iostream>

//For test_boost_foreach()
#include <boost/algorithm/string/trim.hpp>
#include <boost/foreach.hpp>

void test_boostStr() {
    std::vector<std::string> strs;
    boost::split(strs, "string to split", boost::is_any_of("\t "));
    std::cout << strs.size() << std::endl;
    //  std::cout << strs.at(1) << std::endl;
}

void test_boost_foreach() {
    //std::vector<std::string> namespaces_;
    std::string namespaces_  = " tele op eration. ";
    std::cout << "managing namespaces: ";
    std::string out;
    std::string s;
    BOOST_FOREACH(s, namespaces_)
    {
        boost::trim(s);
        out += s + " ";
    }
    std::cout << out.substr(0, out.size() - 1) << std::endl;
}

int main(void) {
    test_boost_foreach();
}

运行结果：

在 Eclipse 的“问题”选项卡中生成结果：

我还没有解决这个问题（似乎在我使用 boost 时经常发生），但根据this thread，根本原因可能在于 Eclipse 的 CDT 插件。如页面中所述，残酷的解决方法是关闭代码分析功能。
