I succeeded to reproduce the crash on the command line. For the tests
shown here I am in the source directory of the current cups-filters,
having run "autogen.sh", "./configure", and "make" already.
After downloading the attached PPD file (comment #11) and the attached
PDF file (comment #7) I have passed the input PDF file through pdftopdf
first, with the following command line:
cat Lauf\ gegen\ Krebs\ 2019.pdf | FINAL_CONTENT_TYPE=application/pdf
PPD=hp_officejet_pro_8620_794b2d_.ppd
DEVICE_URI=implicitclass://hp_officejet_pro_8620_794b2d_/

I am attaching out.pdf. Note that the duplex setting makes pdftopdf add
a blank page to the beginning of the file.
Now I allow core files to be written with
ulimit -c unlimited
and feed out.pdf through pdftoraster using the following command line:
cat out.pdf | FINAL_CONTENT_TYPE=application/pdf
PPD=hp_officejet_pro_8620_794b2d_.ppd
DEVICE_URI=implicitclass://hp_officejet_pro_8620_794b2d_/

I open the resulting core file with gdb:
gdb -c core .libs/pdftoraster
Running the "bt" command within gdb gives the following backtrace:
