Memory leak on call_function

[exphck1337]

Hello, I found a memory leak on this line, whenever call_function is called it's allocate a new page, is missing an if or make the call after the declaration of the variable allocated_shellcode.

Fix:

static void* allocated_shellcode = nullptr;

if ( !allocated_shellcode )
{
    // MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE
    allocated_shellcode =
        VirtualAlloc(nullptr, sizeof( shellcode ), 0x00001000 | 0x00002000, 0x40);

    if ( !allocated_shellcode )
        detail::throw_last_error( 
        "VirtualAlloc failed to allocate memory for call_function shellcode" );
}

Alternative fix:

static void* allocated_shellcode = VirtualAlloc(nullptr, sizeof(shellcode), 0x00001000 | 0x00002000, 0x40);

Hopefully fixed (did it on phone so hopefully didnt't make any mistakes)
