我正在使用 Visual Studio 2019 构建 .NET CORE Web api。当我通过 VS2019 使用 docker 构建应用程序时，出现错误：“Docker 命令失败，退出代码 125”。

知道原因是什么吗？这是输出：

我试图创建read()包装但收到此错误:

错误:第23行'(asm')中的未知寄存器名称'%% ebx'//(粗线)

这是代码:

#include <sys/syscall.h>
typedef unsigned int size_t;
typedef signed ssize_t;

extern int errno;

int main(void) {
    int fd = 0;
    char buf[128];
    size_t count = 128;
    my_read(fd, buf, count);

    return 0;
}

int my_read(int fd, void *buf, size_t count) {
    long ret;

    asm("pushl %%ebx\n\t" // Line 23
