从上述输出中可以看到,程序存在内存泄漏问题。具体情况如下:
- definitely lost: 25,736 bytes in 64 blocks,表示有 64 个内存块被分配但未被释放,总大小为 25,736 字节。
- indirectly lost: 17,292 bytes in 573 blocks,表示有 573 个内存块间接丢失,即这些内存块被分配后的指针丢失,无法再次访问,总大小为 17,292 字节。
- possibly lost: 57,662 bytes in 614 blocks,表示有 614 个内存块可能已经丢失,即这些内存块被分配后的指针没有被释放,但程序结束时可能还可以访问,总大小为 57,662 字节。
- still reachable: 14,027,394 bytes in 87,658 blocks,表示有 87,658 个内存块仍然可以访问,总大小为 14,027,394 字节。
为了找到内存泄漏的地方,可以使用 Valgrind 提供的 "stack trace" 功能来获取指针地址对应的函数调用栈信息。同时,可以使用 --track-origins=yes 选项来查看未初始化的值的来源。需要重新运行 Valgrind,并使用 --leak-check=full --show-leak-kinds=all 选项来查看详细的泄漏信息。最后,需要根据 Valgrind 的输出信息来进行相应的内存泄漏修复工作。

这是 Valgrind 的 LEAK SUMMARY 部分的输出,它提供了程序的内存泄漏信息。具体来说,它提供了以下信息:
- "definitely lost":这是指程序中存在的内存泄漏,即指针指向的内存块已经不可访问,但是程序没有释放该块。在这个例子中,程序中有 64 个内存块,总共 25,544 字节的内存泄漏。
- "indirectly lost":这是指程序中存在的间接内存泄漏,即指针指向的内存块已经不可访问,但是程序没有释放该块,而且没有指向该块的指针。在这个例子中,程序中有 573 个内存块,总共 17,484 字节的间接内存泄漏。
- "possibly lost":这是指程序中存在的可能的内存泄漏,即指针指向的内存块已经不可访问,但是程序没有释放该块,而且没有指向该块的指针。在这个例子中,程序中有 614 个内存块,总共 57,662 字节的可能内存泄漏。
- "still reachable":这是指程序中存在的仍然可达的内存块,即指针指向的内存块已经不可访问,但是程序没有释放该块,而且仍然存在指向该块的指针。在这个例子中,程序中有 87,663 个内存块,总共 14,027,546 字节的仍然可达的内存块。
- "suppressed":这是指程序中存在的被压制的错误,即 Valgrind 检测到了错误,但是被设置为不显示该错误的信息。在这个例子中,没有被压制的错误。
总之,该程序存在内存泄漏,需要修复以避免浪费内存和其他潜在的问题。需要仔细分析 Valgrind 的输出并修复问题。
JVM terminated.Exit code=2
As an AI language model, I do not have access to the specific context of your issue. However, in general, "JVM terminated. Exit code=2" means that the Java Virtual Machine (JVM) has encountered an error and has terminated. The exit code of 2 indicates that there was a problem with the command line arguments or input parameters.
Some possible causes of this error could be:
1. Invalid command line arguments or input parameters
2. Incorrect version of the JVM or Java runtime environment
3. Memory issues, such as insufficient memory or a memory leak
4. Corrupted or missing system files or libraries
To troubleshoot this error, you can start by checking the command line arguments or input parameters, ensuring that they are valid and correctly formatted. You can also try updating your JVM or Java runtime environment, and checking your system for any memory issues or corrupted files. Additionally, checking the logs or error messages generated by the JVM can provide more information on the specific cause of the error.
