           Summary: differences in output between file and pipe output
           Product: GhostPCL
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P4
         Component: PCL interpreter
        AssignedTo: henry.stiles at artifex.com
        ReportedBy: marcos.woehrmann at artifex.com

On my amd64 linux box the following two commands generate different output files:

  pcl6 -r72 -sDEVICE=bitrgb -sOutputFile=test1.bit -dNOPAUSE ./c327.bin
  pcl6 -r72 -sDEVICE=bitrgb -sOutputFile="| cat >test2.bit" -dNOPAUSE ./c327.bin

The differences appear on pages 28 and 29 (see attached screenshots for differences on page 29).

Note that this is not a non-deterministic problems, I've run each command 100 times and each  
md5sum is identical.

I get the same results on my MacBook Pro under Mac OS X, but on the same machine running Ubuntu 
8.10 via VMware Fusion neither command line is deterministic.

I believe this problem is related to bug #690299 since the areas that differ are the same (at least on 
page 29, I've seen differences on page 28 with -r600 and multiple runs but they appear to be 
infrequent).
