The problem is not with compiler, but it seems to be with Boost version.
Simply, boost::tuple is not (yet?) recognised as a fusion sequence, thus
enabling the specialisations for the fusion, causes problems with
boost::tuple support in SOCI.
As far as I know, boost::tuple is not adapted as a regular fusion sequence.
Two simple examples compiled using
gcc (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5
1) First example
#include <boost/fusion/support/is_sequence.hpp>
#include <boost/fusion/container.hpp>
#include <boost/tuple/tuple.hpp>
#include <boost/mpl/assert.hpp>
#include <iostream>
using namespace boost;
int main()
{
BOOST_MPL_ASSERT(( fusion::traits::is_sequence<fusion::vector<int> > ));
BOOST_MPL_ASSERT(( fusion::traits::is_sequence<boost::tuple<int> > ));
}
a) does not compile with Boost 1.42

Back to your patch, compiling SOCI tests with your patch and Boost 1.42
gives nearly exactly the same error as in the case 1) a)

The line common-tests.h:3115 is the first test case using boost::tuple
http://soci.git.sourceforge.net/git/gitweb.cgi?p=soci/soci;a=blob;f=src/core/test/common-tests.h;h=e38d9151d7a3e57c0f8423dc83e0352297e71d93;hb=HEAD#l3115
Having your patch applied, the new fusion support templates interfere
with the tuples.
Which version of Boost do you use?
Have you tried compiling the tests?
