非常类似的问题，如CreateProcessA 函数在 MASM64 (ml64.exe) 中不起作用，但在我的情况下，我认为它不适用于 64x 中的对齐或指针数据类型。所以代码是

    ;ml64.exe CreateProcessA.asm /link /subsystem:console /entry:main /LIBPATH:"C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0\um\x64" /defaultlib:kernel32.lib

extrn CreateProcessA : proc

PROCESS_INFORMATION    struct 
    hProcess          qword ?
    hThread           qword ?
    dwProcessId       dword ?
    dwThreadId        dword ?
PROCESS_INFORMATION    ends

STARTUPINFOA         struct
cb                  qword     sizeof ( STARTUPINFOA )        
lpReserved          qword     ?         
lpDesktop           qword     ?         
lpTitle             qword     ?         
dwX                 dword     ?         
dwY                 dword     ?         
dwXSize             dword     ?         
dwYSize             dword     ?         
dwXCountChars       dword     ?         
dwYCountChars       dword     ?         
dwFillAttribute     dword     ?         
dwFlags             dword     ?         
wShowWindow         word      ?         
cbReserved2         word      3 dup ( ? )
lpReserved2         qword     ?         
hStdInput           qword     ?         
hStdOutput          qword     ?         
hStdError           qword     ?         
STARTUPINFOA         ends

.const
NORMAL_PRIORITY_CLASS equ 020h

.data
processInfo PROCESS_INFORMATION <>
startupInfo STARTUPINFOA <>
szProcName db "C:\Windows\System32\cmd.exe", 00h

.code
    main proc
        lea rax, processInfo
        lea rbx, startupInfo

        push rax                     
        push rbx                     
        push 00h                                  
        push 00h                     
        push NORMAL_PRIORITY_CLASS   
        push 00h                     

        sub rsp, 20h
        mov r9, 00h
        mov r8, 00h
        mov rdx, 00h
        lea rcx, szProcName
        call CreateProcessA

    main endp
end

错误 - kernelbase.dll 中的访问冲突

movaps xmmword ptr ss:[rsp+C0],xmm0

有人可以澄清我的代码有什么问题吗？
