我有以下代码：
#include <memory>
#include <functional>
#include <boost/lockfree/queue.hpp>
#define _ThreadPoolLength_ 100
class thread_pool {
public:
thread_pool() : q(_ThreadPoolLength_) {}
private:
mutable boost::lockfree::queue<std::function<void(int id)> *> q;
};
class Worker
{
thread_pool workerPool;
};
Worker* worker;
int main() {
worker = new Worker();
delete worker;
return 0;
}
如果用 编译它clang++ -fsanitize=address,undefined code.cpp，那么在运行期间它会产生类似的东西：

摘要：UndefinedBehaviorSanitizer：未定义的行为...
我怀疑错误是由 引起的boost::lockfree::queue<std::function<void(int id)> *>，但为什么呢？有没有办法解决它？
clang version 6.0.0-1ubuntu2 (tags/RELEASE_600/final)
最后，我参考了一篇博boost::lockfree::queue<std::function<void(int id)> *>文，用类似的类替换了使用。
