This means that Ghostscript is interchanging objects of different types in
illegal and sleazy ways, or, it is making unportable assumptions about the
sizes of data arguments.
It is certainly doing the exact same thing on DU; but DU is just silent
Both DU and NetBSD fix up the unaligned loads and stores in the respective
kernels, and both then continue the program as if the operation had worked
You can turn off the messages (as root) by doing:
sysctl -w machdep.unaligned_print=0
(Ghostscript works OK for me...)
