Boost Serlialization on XScale problem
Hi, I am having a strange problem with the Boost Serilalizartion library on an XScale platform. I am using v1.34.1 of the libraries and I'm seeing segfaults when creating an archive object, but only under some circumstances. The problem occurs in several different projects, but I've been able to reproduce it using the most simple case from the tutorial (http://www.boost.org/doc/libs/1_36_0/libs/serialization/doc/index.html). The problem that I see is that the code segfaults at these lines, and a core dump shows this error is occuring down on malloc_trim(): std::ifstream ifs("filename"); boost::archive::text_iarchive ia(ifs); // <--- causes a segfault. However, if I move the "std::ifstream ifs("filename");" further up the code (next to the initialisation of the ofs object, then the code works fine. Has anyone else seen any problems like this before? We have been using Boost::Thread, and Boost::Date-Time without any problems for a while, so I believe that this may just be a serialization library problem. I am also going to give v1.36.0 a try to see if it's something subtle that's been fixed already. (I have a core dump that I can make available if anyone needs it....) --lee --
I doubt its a problem with the library but try this: { std::ifstream ifs("filename"); { boost::archive::text_iarchive ia(ifs); // <--- causes a segfault. } } platforms which don't destroy everything in the reverse sequence of creation would have problems which would be addressed by this change.

Thanks for the try Robert, but that still gives the same problem...
I suspect that its a deep seated libc or compiler problem, but the
serialization libraries are the first thing to manifest this problem.
weird.

Hi, I'm trying to build my application in release mode using VC8 and failing with a link error: LINK : fatal error LNK1104: cannot open file 'libboost_thread-vc80-mt-gd-1_34_1.lib' I am including the non-debug version of the thread library and don't want the debug version in there (because that's going to cause other link errors) but have no idea how the debug version is being included in the link. Apologies if this is a little off topic but has anyone had this problem or got any suggestions?

My guess is that _DEBUG is defined for some reason, but the library selection logic is in boost/config/auto_link.hpp, which code generation options are you using? HTH, John.

Thank you John, you've just saved my sanity, _DEBUG was defined in one of the sub projects. ****************************************************************************** "This message and any attachments are solely for the intended recipient and may contain confidential and privileged information.
