Ok, I think I've finally figured out why we are not getting this error
even though we are testing with the same compiler and C++ standard:
while the 2.5.0 pre-release still provides the same std::auto_ptr
specialization in odb/pointer-traits.hxx, it is #ifdef'ed out if
using C++11 or later. Here is the relevant line:

https://git.codesynthesis.com/cgit/odb/libodb/tree/odb/pointer-traits.hxx#n163

Note that this is not the only place like this: I checked and basically
every mention of std::auto_ptr in libodb in 2.5.0 is made conditional
like this.

As a result, I think the easiest way to resolve this is to upgrade
to the 2.5.0 pre-release as described in:
