A question about shell-application's argument make system blocked;

[krishnaLee <sssky307@163.com>]

Hi everybody,
I meet a question,a special arg can make system blocked,follow is my steps.
1,go to uefi shell v2.2(uefi v2.70),run this application in QEMU-ovmf:
testapp.efi
2,the output is "index:0,string:FS0:\testapp.efi"


3,testapp.efi #abc.
4,the output is same as step 2.  ///< I had read the uefi shell specification 2.2,the '#' is a comment remark,so I think it is ok.


5 testapp.efi "#abc"
6,the system blocked(dead).      ///< I think it is a bug.


//follow is the testapp.efi source code:
EFI_STATUS
EFIAPI
UefiMain (
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
{
EFI_STATUS status;
EFI_SHELL_PARAMETERS_PROTOCOL* param;
status=SystemTable->BootServices->HandleProtocol(ImageHandle,&gEfiShellParametersProtocolGuid,&param);
if(status!=EFI_SUCCESS)
{
return0;
}


for(UINTN i=0;i< param->Argc;i++)
{
Print(L"index:%d,string:%s\n",i,param->Argv[i]);
}


return EFI_SUCCESS;
}


//test environment:
//QEMU v2.10.95 + edk2-2018-ovmf-x64.
//shell command line:
//"D:\qemu\qemu-system-x86_64.exe" -machine pc-q35-2.9 -pflash "D:\qemu\bios\OVMF_x64_debug.fd" -serial stdio -hda fat:rw:G:\temp -net none
//end






thanks,
krishna.
