If this is a heavyweight request, contact the Numerical Algorithms
Group (NAG). While they don't have a test suite that does precisely
that, their test suite can and has been used for that. Because of the
size, complexity and reliability of the code - and the fact that it
has an appropriately heavyweight test suite - it is one of the better
stress tests of a compiler of numerical code. But it is not easy to
use and the source is not openly available.

For a lighter weight one, try using LAPACK and even the various
versions of LINPACK. Again, not ideal, but I have used the latter for
that purpose.
