Dear deal.ii community, 

I am testing step-77 using the latest deal.ii release with sundials on 
(version 5.7.0). The example compiles and runs but not as expected, as I 
get the following output:

Mesh refinement step 0
  Target_tolerance: 0.001

[KINSOL ERROR]  KINSol
  The line search algorithm was unable to find an iterate sufficiently 
distinct from the current iterate.

--------------------------------------------------------
An error occurred in line <518> of file 
</home/laura/Local/dealii/source/sundials/kinsol.cc> in function
    unsigned int dealii::SUNDIALS::KINSOL<VectorType>::solve(VectorType&) 
[with VectorType = dealii::Vector<double>]
The violated condition was: 
    status >= 0
Additional information: 
    One of the SUNDIALS KINSOL internal functions returned a negative
    error code: -5. Please consult SUNDIALS manual.

I wonder if this has something to do with my Sundials version or if anybody 
has a hint of what is happenning?

Thank you in advance,

Laura
