Comment:

 I tried to apply the patch of r.terraflow (r.terraflow.diff).  I do not
 know if I did it fine, what I did was to change the original
 "include/iostream/ami_sort_impl.h" file with the modifications in the
 .diff file. If this was fine, below is the output of r.terraflow which to
 me seems to give a different error as before.
