boost::ipc::message_queue does not support 32 process communicate with 64 process

[huyuguang <huyuguang@…>]

The win_msg_hdr_t, msg_hdr_t, win_mq_hdr_t, mq_hdr_t use typedef typename boost::make_unsigned<difference_type>::type size_type;

The sizeof(size_type) is 32 in 32 bit process and 64 in 64 bit process. So when a 32 bit process want to communicate with a 64 bit process, the sizeof(msg_hdr_t) is not equal, which would cause process crash.

Now I

I am so sorry. Please ignore the ticket.

I should use typedef windows_message_queue_t<offset_ptr<void, int, unsigned int> > windows_message_queue32;
