      It crashes with a NULL pbuf, because 'needed' is uninitialized and thus 0xcccccccc. This causes HeapAlloc to fail. The reason it is uninitialized is that GetPrinterW fails with an ERROR_INVALID_HANDLE exception. rpcrt4 prints:

      err:(..\dll\win32\rpcrt4\ndr_contexthandle.c:86) invalid handle 001415D8
