           Summary: setcolorspace + currentgray crashes GS 8.64
           Product: Ghostscript
           Version: 8.64
          Platform: PC
        OS/Version: Windows 2000
            Status: UNCONFIRMED
          Severity: major
          Priority: P4
         Component: Regression
        AssignedTo: support at artifex.com
        ReportedBy: francois.robert at atex.com
         QAContact: gs-bugs at ghostscript.com


The following PS program crashes GPL Ghostscript 8.64 on Win32 :

[ /Indexed /DeviceGray 0 <00> ] setcolorspace currentgray

GS 8.64 (Win32) simply dies with no error message, no mesage box.
GS 8.54 and 8.60 (Win32) returns 0.0 on the stack (as expected ? at least it 
does not die...)

Note: This bug was uncovered when writing a separation procset, where 
currentgray  (and others) are used for probing the existence of nested 
separation contexts.

FYI, another issue was uncovered during those tests :

The following incorrect program :
 
[ /Indexed /DeviceGray 1 <00> ] setcolorspace 

on GS 8.64 produces a cryptic error message :
Error: /rangecheck in -- at 0x10081290--
On GS 8.54 and 8.60, it produces (as expected) :
Error: /rangecheck in --setcolorspace--
