sample pdf

Hi

Attached pdf lets pdftops 0.45.0 work 2 1/2 hours on the conversion to
Postscript on 64-bit Linux.
command: pdftops runsforever-poppler.pdf

$  pdftops runsforever-poppler.pdf
$ date
Wed Jun 29 16:28:46 CEST 2016
$

The original PDF is 10MB, the resulted .ps 67MB


Most pdf files can be converted withing few minutes with pdftops.
It looks like pdftops is looping somewhere or some recursion or loop is not
implemented optimally.

Is it possible that this will be corrected in the near future?

Thank you
Urs
