Thank you for reporting this issue. I believe I have identified the
problem and I will release an update that fixes it shortly. This bug was
caused by an incomplete fix for CVE-2018-16543. In CVE-2018-16543.patch
the line

0 mark /PageSize currentdevice /PageSize //.gsgetdeviceprop .dicttomark

had to be changed to

0 mark /PageSize currentdevice /PageSize //.gsgetdeviceprop exec .dicttomark

Regards,

Markus
