Issue 1427: Results of dndrv1 example depends on NCV

Reported by Alexander Teplukhin, Apr 25, 2014

Steps to reproduce the problem:
1. Take original example dndrv1.f.
2. Run with different ncv, I took a range from 6 to 20.

Expected result:
  Four requested eigenvalues must be the same, i.e. independent of 
ncv.

Actual result:
  Despite incorrect ordering (known issue) four requested values the 
results are inconsistent.

Attached you can find:
 dndrv1.f file where ncv is taken from command line to simplify 
testing.
 dndrv1.xlsx file with results
