Windows 二进制文件在 CMD 上工作但不（总是）在 ProcessBuilder 上工作

Question

我开发了一个 C++ 应用程序，我想从我的 Java 应用程序中调用它。为此，我使用 ProcessBuilder:

ProcessBuilder processBuilder = new ProcessBuilder(command);
processBuilder.redirectErrorStream(true);
Process process = processBuilder.start();
String processOutput = readFromProcess(process);

val exitCode = process.waitFor();
if (exitCode != 0)
{
    // Exception
}

return processOutput;

以下是我读取过程输出的方式：

public static String readFromProcess(Process process) throws IOException
{
    StringBuilder stringBuilder;
    String lineSeparator = lineSeparator();
    try (BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream())))
    {
        stringBuilder = new StringBuilder();
        String line;
        while ((line = bufferedReader.readLine()) != null)
        {
            stringBuilder.append(line);
            stringBuilder.append(lineSeparator);
        }
    }

    return stringBuilder.toString().trim();
}

我得到：

exit code -1073741819 (0xC0000005)

这似乎意味着 The application was unable to start correctly，我什至没有在 EXE 代码的开头得到初始版权控制台打印。

如果我运行 CMD 上的 EXE 相反，它会运行成功，即使我传递了完全相同的参数。为什么会这样？我编译了 Linux 和 Mac OS X 的代码，但它们运行通过 Java 和 Terminal 在各自的操作系统上都很好。提到的退出代码 0xC0000005 只出现在 Windows 而不仅仅是在我的电脑上。其他 2 位用户也发现了这个问题。有时 Windows EXE 仍然会从 Java 运行尽管这更奇怪。

我使用的C++编译标志是：

原来传递的参数不一样，因为 Java 将空字符串解释为 Windows 上没有参数。因此，它索引了超出范围的参数数组，并且仍然拒绝打印内存错误发生之前的任何内容，这是不直观的。
