[Bug c++/37306] New: code generation error

["mlandis at pnmx dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Version 4.3.0 20080428 (Red Hat 4.3.0-8)
the following code:

double* dr = new double[ nn ];
double aa = 28.68, bb=28.35;    // any numbers will do, the point is
                                // these numbers don't have large exponents
...
*(dr+ii) = (aa - bb) / bb;      // produces anomalous results w/large exponents

double xx = (aa - bb) / bb;     // work
*(dr+ii) = xx;                  // around

I had another example, but lost track of it after working around it, but it
also involved dealing with intermediate arithmetic results.
