valgrind 分析死锁

1，安装

 sudo apt  install valgrind 

2，代码pthread.c

#include <stdio.h>
#include <pthread.h>
#include <unistd.h>

pthread_mutex_t lock1 = PTHREAD_MUTEX_INITIALIZER;
pthread_mutex_t lock2 = PTHREAD_MUTEX_INITIALIZER;

void* thread_func1(void* arg) {
    pthread_mutex_lock(&lock1);
    printf("Thread 1: Locked lock1\n");
    sleep(1); // 模拟一些工作
    pthread_mutex_lock(&lock2);
    printf("Thread 1: Locked lock2\n");
    pthread_mutex_unlock(&lock2);
    pthread_mutex_unlock(&lock1);
    return NULL;
}

void* thread_func2(void* arg) {
    pthread_mutex_lock(&lock2);
    printf("Thread 2: Locked lock2\n");
    sleep(1); // 模拟一些工作
    pthread_mutex_lock(
