Description M.J.G. 2022-09-13 10:03:17 UTC 
Apparantly, the fix for bug #703013 may have broken some devices, in particular x11cmyk x11gray2 x11gray4 give a seg fault when doing (i= one of those, others work):

gs  -dBATCH -dNOPAUSE -sDEVICE=$i -sOutputFile=/dev/null dummy.pdf >/dev/null

I bisected this to commit 270438bfda60.

Maybe the comment (above the changed lines) was right after all, and the real fix should be in get_params wrapper or such?

Thanks a bunch for the fix!

Confirmed to work as backport on 9.56.1 also (as expected).
