Same result as written before.

Hmm... I already tried that... but it didn't work either..
The strange thing is that I can do this without trouble:
std::cout << prod(dG,v) << std::endl;
and it actually works without trouble.
But the assignment really "blocks" everything. I have no trouble with it
some places, but this particular spot in the source code messes things
up using -O2 optimization together with my qt-application!
BUT... I don't know what have happened... I've upgraded my compiler to
gcc 4.1.2 and it didn't work two hours ago - even after the upgrade.
Now after having rebooted the computer and started again - it seems to
work... everything!
I'll try to dig deeper and try shifting back to gcc 4.1.1-r3 (gentoo) to
see what have happened.
