Boost :

I don't know who (if anyone?) is maintaining ublas at present, but test4 and
test5 are failing *on every single compiler* at present.

I've partly traced the problem: an exception is being thrown in banded.hpp
line 192, in :

> >::operator()(unsigned int i=0x00000000, unsigned int j=0x00000001) Line
192 + 0x34 C++

The cause is that the member data member _upper has been initialised to
zero, which means any attempt here to access members of the matrix results
in an exception being thrown!

At present I'm stumped, I haven't been able to figure out what the code is
supposed to do well enough to even begin to suggest a fix, so I'm just
hoping this will ring a bell with someone, who'll know what to do :-)
