The problem is caused by the pdftopdf CUPS filter which is based on Poppler, so no Ghostscript bug.
To reproduce ps2pdf DIMACS_Fo_Go.ps This generates DIMACS_Fo_Go.pdf which is displayed correctly by evince or gs. cupsfilter -m application/vnd.cups-pdf -p /etc/cups/ppd/<yourprinter>.ppd DIMACS_Fo_Go.pdf > out.pdf out.pdf shows blank pages when displayed with gs and only a few characters when displayed with evince. On the terminal appear a lot of error messages in both cases. pdftopdf is a part of the CUPS package and it uses Poppler.
