Running POSTHOLE_edited.out on a Mac via Terminal lets you input all important parameters (input-file, out-put file, minimal distance, maximal distance, tolerance) but then finishes off with the following error message, originating at line 283:

Fortran runtime error: Index '2' of dimension 1 of array 'indx' above upper bound of 1

Obviously, 2 > 1 is the problem, but why is the upper bound at 1 at all?!

The original Fortran-code writes to and reads from scratch to form a list of the rectangles found. For CRAN, this is highly problematic and will likely prevent its aceptance as CRAN-package:

Compiled code should not call entry points which might terminate R nor write to stdout/stderr instead of to the console, nor use Fortran I/O nor system RNGs.

The obvious solution is to exit the Fortran-code to test for possible rectangles and write to the rectangle-list in R, and then return to the loop in Fortran. BUT: Is this possible at all (or desirable)?
