我只是调试一个大项目而且收到此错误
*** glibc detected *** p_appmanager/obj/appmanager: corrupted double-linked list: 0x08325e18 **
我曾尝试用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消息的含义吗？

答案 0 :(得分：29)
看起来线程正在打印已在主（或另一个）线程上释放的数据（char*字符数据）。
更具体地说，Parser::parse构建了vector个std::string。

我注意到其他backtracecs都突出显示了相同的模式。
显然，某些线程已启动，并且它们会将引用（in）传递给这些字符串。但是，由于向量是Parser::parse的本地（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std::ostream::operator<<(std::ostream&, const char*) <流式传输字符串时/ em>的）。
遗憾的是，堆栈跟踪并不能完全显示哪个名称/对象模块包含有问题的行，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，线程会将{em>引用带到string s（来自向量），因为线程也< / strong>尝试将字符串分配给另一个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string甚至没有足够长的时间让本地副本工作。
IOW。似乎一个线程正在启动：
#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";
}
这里出现相同的竞争条件，因为对“即将过期”数据的引用被传递给线程：
async(some_background_worker, ref(data));
它在我的系统上与bad_alloc崩溃（这是假的，但是非常精细的未定义行为）。
如上所述， 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 仍然 是数据竞赛，因为（没有明确的同步），无法保证ref_data是即使在那时也有效。
通过将数据移动到线程中来修复它：
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，它会运行并打印
result of worker: 9
result of worker: 32389
result of worker: -42
result of worker: 42
完全符合预期。看到它正在运行 live at Coliru
