C 如何理解调用MPI_Abort时的输出？

我正在编写一个简单的MPI程序，当我们调用MPI_Abort时，我对输出感到困惑

代码是

// main.cpp
#include "mpi.h"
#include <stdlib.h>
#include <stdio.h>

int main(int argc, char **argv)
{
    MPI_Init(&argc, &argv);
    int x = 1;
    if (x == 1)
    {
        MPI_Abort(MPI_COMM_WORLD, -100);
    }
    MPI_Finalize();
    return 0;
}

操作系统是Ubuntu 18.04 编译器为MPICH，终端中的类型

mpic++-v

可以获取编译器的详细信息：

如果我通过follow命令运行可执行文件 输出是

application called MPI_Abort(MPI_COMM_WORLD, -100) - process 0
[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=-100
:
system msg for write_line failure : Bad file descriptor

application called MPI_Abort(MPI_COMM_WORLD, -100) - process 0
[cli_0]: readline failed

如何理解写行错误？写线故障？到底发生了什么

感谢您抽出时间。

请启用编译器中的所有错误和警告。然后读取编译过程的输出。修复报告的问题。如果您不理解/不知道如何修复某个问题，请在此处提问。从您的简短描述中，我们很难理解发生了什么。您使用的是哪个MPI库（供应商和版本）？MPI库是MPICH 3.3A2没有编译器警告
