libc++abi: terminating with uncaught exception of type std::out_of_range: basic_string

This error message suggests that there is an unhandled exception of type std::out_of_range in the code, specifically related to a basic_string object. The std::out_of_range exception is thrown when an attempt is made to access an element outside the valid range of a container (such as a string or an array).

To resolve this issue, you will need to locate the source of the exception and handle it appropriately. This may involve checking the range of indices being used to access a string or array, or adding exception handling code to catch and handle the exception.

libc++abi: terminating with uncaught exception of type std::bad_alloc: std::bad_alloc zsh: abort

这个错误信息表明程序在运行时遇到了std::bad_alloc异常，这通常是由于程序试图分配的内存超出了操作系统或程序所允许的范围。这个异常通常会导致程序崩溃并终止运行。

要解决这个问题，可以尝试以下几种方法：
1. 检查程序中是否有内存泄漏或者过度分配内存的情况，可以使用内存分析工具来帮助检测。
2. 尝试减少程序中对内存的使用，例如使用更高效的算法或数据结构。
3. 增加系统内存或者调整程序的内存限制，以便程序可以分配更多的内存。

libc++abi: terminating with uncaught exception of type std::__1::system_error: condition_variable wait failed: Invalid argument

This error occurs when a condition_variable is waiting for a notification, but the underlying condition is not valid. This can happen if the function is called with an invalid argument or if the condition was not initialized properly.

To fix this error, you need to check the arguments being passed to the condition_variable and ensure that they are valid. You may also need to initialize the condition properly before using it.

Here's an example of how to use a condition_variable:

#include <iostream>
#include <condition_variable>
#include <mutex>
#include <thread>

std::condition_variable cv;
std::mutex mtx;
bool ready = false;

void thread_func()
{
    std::unique_lock<std::mutex> lock(mtx);
    ready = true;
    cv.notify_one();
}

int main()
{
    std::thread t(thread_func);

    std::unique_lock<std::mutex> lock(mtx);
    while (!ready) {
        cv.wait(lock);
    }

    t.join();
    return 0;
}

In this example, we create a condition_variable named `cv`, a mutex named `mtx`, and a boolean flag called `ready`. We start a new thread that sets the `ready` flag to true and notifies the condition_variable. In the main thread, we wait for the notification by calling `cv.wait(lock)` in a loop.

Note that we need to acquire the lock before calling `cv.wait()` or `cv.notify_one()`. This ensures that the condition is modified atomically and prevents race conditions.

If you are still experiencing the error after checking your code, you may need to consult the documentation for the specific function that is throwing the exception to see if there are any known issues or limitations.
