Comment:

 I would not call this a "major" defect.  It would not fail in a production
 environment as NDEBUG would be defined.  It does point out some scaling
 issues which could cause problems.  Should there be no checking? lower
 bounds of -1.0e20 OK? -1.0e30?

 Have modified code to 1.0e20 - hopefully will still help people debug
 their projects.
