这是我第一次使用汇编。当我运行程序时，我收到此错误：
zsh: segmentation fault (core dumped) ./t
我认为问题在于它试图访问（或执行）不允许的内存。
正如我所说，这是我第一次，不知道问题出在哪里。谢谢！
这是我运行它的命令：
nano -c t.asm && nasm -f elf32 t.asm && ld -melf_i386 -s -o t t.o && ./t
这是t.asm：
; This is a simple program to read through a file and output vowels
; to stderr, and constants to stdout.
