debugging debug

Might this be related to recent work on debugging tools?

Here's more info on my debug issue.

My code doesn't explicitly use debug or error stuff.  It has these includes:

#include "linbox/util/timer.h"
#include "linbox/matrix/sparse-matrix.h"
#include "linbox/matrix/dense-matrix.h"
#include "linbox/ring/modular.h"
#include "linbox/algorithms/blackbox-block-container.h"
