Boost C++ Libraries: Ticket #9414: boost::ipc::message_queue does not support 32 process communicate with 64 process https://svn.boost.org/trac10/ticket/9414 <p> The win_msg_hdr_t, msg_hdr_t, win_mq_hdr_t, mq_hdr_t use typedef typename boost::make_unsigned&lt;difference_type&gt;::type size_type; </p> <p> 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. </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9414 Trac 1.4.3 Ion Gaztañaga Thu, 21 Nov 2013 20:18:03 GMT status changed; resolution set https://svn.boost.org/trac10/ticket/9414#comment:1 https://svn.boost.org/trac10/ticket/9414#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">invalid</span> </li> </ul> Ticket
