Hello, currently these tests fail for a wide range of compilers. I fired up a debugger and had a look at the core file produced by the test on Tru64/CXX. Here are the results: (ladebug) where

Going to stack frame #8 gives:

8 0x12003dc84 in __7throw_exception__tm__37_Q3_5boost7archive17archive_exception__5boostFRCZ1Z_v(e=& class boost::archive::archive_exception { ... }) "../../../boost/throw_exception.hpp":39 39 throw e;

And finally: (ladebug) print e & class boost::archive::archive_exception { code = unregistered_cast; } Maybe this helps in finding the source of the failure. I can provide more info if needed. Regards, Markus
