Well, I have found one problem: gcc has a bug with its
ostringstream::tellp() function in versions prior to 3.4:

    http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10975

We were using that function, and it was definitely causing problems.
But with a workaround in place, we're still seeing the crashes.

The real problem is that boost is generating an exception.  We are
using portable_binary_[io]archive.hpp from the
libs/serialization/example directory (in the boost 1.33
distribution).

Near line 67 of portable_binary_iarchive.cpp, there's a check.  If
the check fails, then it throws the
portable_binary_archive_exception().

I don't really understand the code at this point, particularly how
istream::get() is used.

Thanks again,
Matt
