Boost C++ Libraries: Ticket #1998: Possible bug in Boost.MPI on 64 bit machines https://svn.boost.org/trac10/ticket/1998 <p> I have a simple program that performs an <strong>mpi::broadcast</strong> of an object of a user-defined class.<br /> While the program runs with no error on a CentOS 5.1, 32 bit, machine, it crashes on a CentOS 5.1, 64 bit machine (segmentation fault). The MPI implementation I use it's mpich2-1.0.6p1.<br /> It seems there's some problem with the packed_iarchive (I checked with valgrind). I cannot find any error in my code (it's nearly 3 days that I'm trying to find if there is an error in my code, but I don't see any error).<br /> The program attached crashes with more than one process. It does not crash if you activate the second dataset (uncomment lines 153-154 and comment lines 150-151).<br /> I'm using Boost 1.35.0, checked out from the svn repository. </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/1998 Trac 1.4.3 MIchele De Stefano <micdestefano@…> Mon, 09 Jun 2008 09:44:33 GMT attachment set https://svn.boost.org/trac10/ticket/1998 https://svn.boost.org/trac10/ticket/1998 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">main.cpp</span> </li> </ul> <p> Small test program for the bug </p> Ticket MIchele De Stefano <micdestefano@…> Tue, 10 Jun 2008 07:11:49 GMT <link>https://svn.boost.org/trac10/ticket/1998#comment:1 </link> <guid isPermaLink="false">https://svn.boost.org/trac10/ticket/1998#comment:1</guid> <description> <p> Actually, I discovered that the bug is not a Boost.MPI bug, but it is a Boost Serialization bug.<br /> I will report it in a new ticket.<br /> Sorry for this<br /> </p> </description> <category>Ticket</category> </item> <item> <dc:creator>Daryle Walker</dc:creator> <pubDate>Wed, 11 Jun 2008 22:52:53 GMT</pubDate> <title>status changed; resolution set https://svn.boost.org/trac10/ticket/1998#comment:2 https://svn.boost.org/trac10/ticket/1998#comment:2 <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">duplicate</span> </li> </ul> <p> Refer to the <a class="closed ticket" href="https://svn.boost.org/trac10/ticket/2002" title="#2002: Bugs: bugs in load_binary and save_binary on 64 bit machines (closed: invalid)">underlying bug</a> instead </p> Ticket Mon, 03 Nov 2008 14:20:34 GMT milestone deleted https://svn.boost.org/trac10/ticket/1998#comment:3 https://svn.boost.org/trac10/ticket/1998#comment:3 <ul> <li><strong>milestone</strong> <span class="trac-field-deleted">Boost 1.35.1</span> </li> </ul> <p> Milestone Boost 1.35.1 deleted </p> Ticket
