hook is called on 0x4A1FA0, using the old m1 client

DWORD ConsoleTextJmpBack = 0x4A1FA5;

void __declspec(naked) PrintHookStub()
{
	char* FirstArg;
	char* TextBuffer;

	__asm{
		pop FirstArg
		pop TextBuffer
	}

	ProcessText(TextBuffer);

	__asm{
		push TextBuffer
		push FirstArg
		mov eax, 800h
		jmp ConsoleTextJmpBack
	}
}

I get an access violation exception
