Reproducible: Always Steps to Reproduce: 1. { LANG=C args='-dBATCH -dSAFER -dNOPAUSE -sDEVICE=tiffg4 -sOutputFile=- /usr/share/doc/packages/ghostscript-library/examples/chess.ps' && set -o pipefail && gs $args >/tmp/chess1.tiff && gs $args | cat >/tmp/chess2.tiff && { diff /tmp/chess{1,2}.tiff; } } 2. 3. Actual Results: 1. Files /tmp/chess1.tiff and /tmp/chess2.tiff differ Expected Results: 1. strace gs shows: lseek(1, 7, SEEK_SET) = -1 ESPIPE (Illegal seek) This should be a fatal error but it does not cause the tiffg4 driver to fail. It happily continues to produce invalid data. I would have posted it to Artifex Bugzilla directly but I am still blocked as a troll (whistleblower) in because of Bug 608071. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
