Bug 691717

The customer reports and I've verified that GhostPCL 8.70 and head (r11850) seg fault when reading the attached PCL file.  I currently do not have access to an HP PCL printer, so can't verify that this is a legitimate PCL file, but in any case GhostPCL shouldn't seg fault.

The command line I'm using for testing:

  pcl6 -sDEVICE=ppmraw -sOutputFile=test.ppm ./00010.SPL


Here's the stack trace from gdb:
