I have downloaded 2.5.0.a1 from your tmp directory, applied the 2 commits
 " Export container and section traits" and "Make sure we don't match
namespace ::foo as prefix" after that.

I bootsraped, configured, make, make installed for all of libcutl, odb,
libodb, -boost and -sqlite (in /usr/local/....)
/usr/loca/bin/odb --version is indeed 2.5.0.a1

This statement in c++11:

using derived_frombase = cloneable<base,derived>;   // crashes
#pragma db object(derived_frombase) abstract definition
#pragma db object(derived) table("derivedobjects") definition  // derived
derives from base through cloneable

crashes the compiler with the backtrace below. I made sure
/usr/local/include is set as -I flag for the odb compiler. (Note I still
have odb 2.4.0 from the rpm package installed, and i have 2.5 in /usr/local)

As I have the odb sources now, i am able to quickly test out any fix you
may think of. Thanks
