损坏的双链表？

Question

我只是调试一个大项目,并得到这个错误

*** glibc detected *** p_appmanager/obj/appmanager: corrupted double-linked list: 0x08325e18 **

我试图用valgrind调试代码,但我对这个工具并不熟悉.所以如果你能从他们那里找到任何东西,我会把这些日志倾倒在这里请告诉我.

任何人都可以解释以下错误信息可能意味着什么？

看起来线程正在打印char*已在主(或另一个)线程上释放的数据(字符数据).

更specificly,Parser::parse建立一个vector的std::string秒.

我注意到其他backtracecs都突出显示了相同的模式.

显然,一些线程开始了,它们被传递给这些字符串的引用(in).但是,由于向量是本地的Parser::parse(可能是自动变量,或明显删除),因此引用不再有效(例如,在使用流式传输字符串时std::ostream::operator<<(std::ostream&, const char*)).

遗憾的是,堆栈跟踪并不能完全显示哪个名称/对象模块包含违规行,但您可以看到它存在于一个单独的线程上(由于存在start_thread)

编辑显然,螺纹(或多个)需要参考到string秒(从向量),因为线程也试图指定的字符串到另一个string.

这可能表明程序员意识到refence不可靠并尝试将其复制到线程局部变量.也许只是因为涉及竞争条件而且strings甚至没有足够长的时间让本地副本工作.

督察.看起来线程正在这样启动:

#include <future>
#include <algorithm>
#include <sstream>
#include <iterator>
#include <iostream>

using namespace std;

// sample: return the largest integer value or 42
int some_background_worker(vector<string> const& ref_data)
{
    if (ref_data.empty()) return 42;

    vector<int> values(ref_data.size());
    transform(begin(ref_data), end(ref_data), begin(values), 
            [](string const& s) { return stoi(s); });
    return *max_element(begin(values), end(values));
}

struct Parser
{
    future<int> parse(string const& msg) const
    {
        istringstream iss(msg);
        istream_iterator<string> f(iss), l;

        const vector<string> data { f, l };

        // now dispatch a thread to do the work
        return async(some_background_worker, ref(data));
    }
};

int main() // mimicks your "fifoThread" function
{
    // we use a simple vector to stub your fifo queue:
    const std::vector<string> fifoQueue { "1 3 9 -1 2", "32389 3102 -34 -888", "-42 -889", "" };

    vector<future<int>> results;

    {
        Parser parser;
        for(auto& msg : fifoQueue)
            results.push_back(parser.parse(msg));
    }

    // all parser data has been throroughly destroyed, before we might even
    // start the workers
    for(auto& fut: results)
        std::cout << "result of worker: " << fut.get() << "\n";
}

在这里,出现相同的竞争条件,因为对"即将过时"数据的引用被传递给线程:

async(some_background_worker, ref(data));

它bad_alloc在我的系统上崩溃了(这是假的,但非常精细的未定义行为).

就像我上面说的那样,std :: string :: assign调用可能表示线程尝试在本地复制数据,如:

vector<string> local_copy(ref_data);

但这仍然是数据竞争,因为(没有明确的同步)ref_data即使在那一点上也不能保证有效.

通过将数据移动到线程来修复它:

int some_background_worker(vector<string> data);

// and then, in parse(...):
    async(some_background_worker, std::move(data));

现在,在我的系统上,它运行并打印

result of worker: 9
result of worker: 32389
result of worker: -42
result of worker: 42

完全按预期.看到它在Coliru现场直播
