I am trying to compile a module for automatic differentiation. The file is
called auto_deriv.f90 and is distributed by the journal Computer Physics
Communications at http://www.cpc.cs.qub.ac.uk/summaries/ADLS_v1_0.html .
However, when trying to compile this with gfortran -c auto_deriv.f90 I get:

 In file auto_deriv.f90:2757

END MODULE deriv_class
 Internal Error at (1):
 spec_dimen_size(): Bad dimension

I have absolutely no idea why this happens. Just in case it is helpful there is
an HTML version of the associated paper available online at
