More likely a bug introduced by recent improvements in handling automatic registering/deregistering.
Please make a small test case (below isn't complete) along with information about compiler, os,
etc and open up a TRAK item.

Folks,
I'm running some serialization unit-tests which pass with flying colors under 1.35.0 and earlier, however they seg-fault on exit when run through 1.36.0.
The error appears to deal with destruction of extended_type_info_typeid objects, and *only* manifests itself when I load an archive through a shared_ptr<T>. The load will appear to function properly, then on exit of the application, <<Death>>. This occurs even if I remove BOOST_CLASS_EXPORT && BOOST_CLASS_TYPE_INFO as the shared_ptr is to the derived element, and I'm not testing through a base.
My lastest guess is that I may be missing some #define BOOST_SOME_MAGIC_NEW_OPTION
//////////////////////////// pseduo code: ////////////////////////////

my_pack< MyTestClass >( os, outtie );
os.close();
std::ifstream is( "MyTestClass_Serialization.xml", std::ios_base::in );
my_unpack< MyTestClass >( is, innie );
is.close();
