The following is sufficient to reproduce for me:

debugobj/gs -sDEVICE=cups -o /dev/null -dcupsColorSpace=1 pdf-testpage-a4.pdf

valgrind reports some unitialized value decisions in the garbage collector
before the final attempt to execute a null transform proc. Running with -dNOGC
the segfault still happens, but the gc report is replaced by several hundred
unitialized value warnings in errprintf called from cups_put_params.

Since the file runs ok with other devices, the cups parameter handling
clobbering memory seems a likely place to look.
