Test case - needs to be linked against -lgsl -lgslcblas

Options: "" or "-g". (Using -fcheck=all caused an ICE, cf. PR 50718.)

Reduced version attached - still needs the GSL to be linked:

$ gfortran-4.5 test.f90 -lgsl -lgslcblas && ./a.out
           0   8.0000000000000000     
$ gfortran-4.6 test.f90 -lgsl -lgslcblas && ./a.out 
           0   8.0000000000000000
