Bug 186938 – app-text/ghostscript-esp - gs produces wrong output when use pipes

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Immo 'FaUl' Wehrenberg 2007-07-28 21:58:54 UTC]

while
gs -q -dSAFER=true -sPAPERSIZE=a4 -dNOPAUSE -sOutputFile=- -sDEVICE=tiffg3 -dBATCH amokformular.pdf > amok2.tiff
produces absolute perfect output, the output from
gs -q -dSAFER=true -sPAPERSIZE=a4 -dNOPAUSE -sOutputFile=- -sDEVICE=tiffg3 -dBATCH 
amokformular.pdf | cat > amok2.tiff
is broken. The same happens at least with python and tee, i did not try out other programms. The output differs very little, but enough to break everything. I have no idea what this can cause (upstream?). 

Reproducible: Always

Steps to Reproduce:
use 
gs -q -dSAFER=true -sPAPERSIZE=a4 -dNOPAUSE -sOutputFile=- -sDEVICE=tiffg3 -dBATCH  <File>.pdf | cat > <name>.tiff and gs -q -dSAFER=true -sPAPERSIZE=a4 -dNOPAUSE -sOutputFile=- -sDEVICE=tiffg3 -dBATCH <File>.pdf > <name>.tiff 
and compare the output.
Actual Results:  
output-files differ

Expected Results:  
output-files should be the same

Which ghostscript implementation and version is this about?

[Comment 2 Immo 'FaUl' Wehrenberg 2007-07-29 10:18:36 UTC]

this behaviour is at least seen on on ghostscript-esp-8.15.3 and ghostscript-esp-8.15.4

[Comment 3 Peter Volkov (RETIRED) 2009-05-26 06:12:17 UTC]

ghostscript-esp was removed from the tree.
