Trying to convert MASM into C equivalent, but getting different result

Question

I was trying to convert this MASM code

.386
.model flat, stdcall 
.stack 4096
assume fs:nothing

.code 
    main proc
            mov eax, [fs:30h]           ; Pointer to PEB (https://en.wikipedia.org/wiki/Win32_Thread_Information_Block)
            mov eax, [eax + 0ch]        ; Pointer to Ldr
            mov eax, [eax + 14h]        ; Pointer to InMemoryOrderModuleList
            mov eax, [eax]                ; this program's module
            mov eax, [eax]                ; ntdll module
            mov eax, [eax -8h + 18h]; kernel32.DllBase
            
            mov ebx, 0                    ; just so we can put a breakpoint on this
            int 3
    main endp
    end main

which finds Kernel32 dll base, into C equivalent. This is my try:

    asm("mov %fs:0x30, %eax\n"); // PEB
    asm("mov 0x0c(%eax), %eax\n"); // LDR
    asm("mov 0x14(%eax), %eax\n"); // InMemoryOrderModuleList
    asm("mov %eax, %eax"); // this program's module
    asm("mov %eax, %eax"); // ntdll module
    asm("mov -0x8(%eax), %eax"); // kernel32.DllBase
    asm("mov 0x18(%eax), %eax"); // kernel32.DllBase
    asm("mov %%eax, %0 \n" : "=r"(i));
    asm("int3");
    printf("kernel32.DllBase: %p\n", i);

The compiler I'm using is i686-w64-mingw32-gcc.

For some reason the code I wrote returns wrong address. The address it returns points to ntdll.
