求解，gcc编译C++代码为intel样式错误

Question

c++代码

 int g_arr[10];

 int main()
 {
  g_arr[0] = 1;
  g_arr[1] = 2;
    g_arr[2] = 3;
 }

使用g++编译为intel样式的汇编代码
g++ -S -o main.s main.cpp -masm=intel
然后汇编为目标文件时报错
g++ -c -o main.o main.s

查看编译后的汇编代码确实有问题，不知道是不是编译参数写错了还是gcc使用intel样式汇编时本身就有bug

我试过了，正常编译没问题 g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-18)

 int g_arr[10];

int main()
{
        g_arr[0] = 1;
        g_arr[1] = 2;
        g_arr[2] = 3;
        return 0;
}

main.s

    .file   "main.c"
    .intel_syntax noprefix
.globl g_arr
    .bss
    .align 32
    .type   g_arr, @object
    .size   g_arr, 40

    .zero   40
    .text

    .type   main, @function
