I looked at your database and it is unlikely you are really running
out of memory. So this most likely a memory corruption. Try to run
your application under a memory checking tool. I am not sure what's
the options are on Windows, on Linux you could try valgrind or an
address sanitizer.

Another thought: check that your are not loading the same object
recursively (e.g., via a cyclical relationship). If that's the
case, then use odb::session (see the manual for details).
