           Summary: clist error in fts_41xx.xps and fts_39xx.xps
           Product: Ghostscript
           Version: HEAD
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Graphics Library
        AssignedTo: leonardo at artifex.com
        ReportedBy: ralph.giles at artifex.com
         QAContact: gs-bugs at ghostscript.com


The xps interpreter fails in the clist code with two files from the Quality
Logic functional test suite. Tracing through the code, they both ultimately
reach clist_writer_check_empty_cropping_stack()with a non-NULL cropping stack,
which throws an unregistered error.

Running -Zv shows an unbalanced 'clist_fill_path: restore' before the final
gs_end_transparency_group where the error occurs.

Example command lines for reproducing the problem:

xps/obj/gxps -n -Zv -sDEVICE=jpeg -sOutputFile=fts_39xx.jpg -r300 fts_41xx.xps
xps/obj/gxps -n -Zv -sDEVICE=jpeg -sOutputFile=fts_39xx.jpg -r300 fts_39xx.xps

It also shows on the cluster regression runs with the ppmraw device.
