Arm64平台std::function触发SIGILL_ILLOPC崩溃求助

运行环境为Arm64平台，使用gcc 6.4版本编译，程序在部分客户机器上持续在Task::Task构造函数处触发SIGILL_ILLOPC崩溃，相同ELF文件在其他机器运行正常，且无法复现该问题，但持续收到客户反馈。原以为ILLOPC仅在交叉编译出错时出现，本次并非如此。

相关代码逻辑 #

template <typename T, typename F, typename ...Args>
Timer::registerTimerTask(T interval, F func, bool once, Args... args) {
    auto t = std::chrono::duration_cast<std::chrono::nanoseconds>(interval);
    auto f = [=]() mutable {func(args...);};
    auto task = std::make_shared<Task>(f, t, once);
    addTask(task);
}
Task::Task(std::function<void()>func, std::chrono::nanoseconds timeout, bool once=false):
     mFunc(func), mTimeout(timeout), mOnce(once) {}

无法理解该崩溃的触发原因，也未找到类似案例，特此求助。
