Description Frank Heindörfer 2005-11-18 04:52:40 UTC 
Ghostscript crashes with a GPF. Tested on different Windows systems on different
machines.

To reproduce this behaviour do this (on a WinXP-SP2): 
1.) Open paint.
2.) Go to image/setting and choose for colors black/white.
3.) Print it with the adobe postscript printer driver in a postscript file.
4.) Convert this postscript file to a pdf file with this parameter file.
-IC:\GS8.53\gs8.53\Lib\;C:\Gs8.53\Fonts\;C:\GS8.53\gs8.53\Resource\
-q
-dNOPAUSE
-dSAFER
-dBATCH
-sDEVICE=pdfwrite
-dCompatibilityLevel=1.3
-r600x600
-dConvertCMYKImagesToRGB=true
-sOutputFile=crash.pdf
-f
test.ps

5.) AFPL Ghostscript 8.51, 8.52, 8.53 crashes. The problem is the parameter
-dConvertCMYKImagesToRGB=true

This doesn't happen with AFPL Ghostscript 8.50 or GPL Ghostscript 8.15.

Test files (postscript file and parameter file) are available. Send me an email
if this is necessary.

Best regards,
Frank
