It used to work on 8.63 and before!!!!

Comment 3 Ray Johnston 2009-02-12 14:42:48 UTC

This was fixed by rev 9452 which, unfortunately did not make the 8.64 release.

The next scheduled release is August. We may do a interm release sooner than
that, but this isn't decided.

Comment 8 Till Kamppeter 2009-02-18 11:14:45 UTC

I can confirm the fix, but the attached patch is broken. I have simply replaced
base/gdevbit.c by the file from trunk (diff is VERY similar) and it worked.
Tested with the test case of the Ubuntu bug report
(https://bugs.edge.launchpad.net/ubuntu/+source/ghostscript/+bug/331127) and
also being able again to print on the HP Color LaserJet 2600n with Rick's driver.

Thanks, Rick, for reporting this, and thanks, Ray, for supplying the patch.

Replacement for the attached patch. This is the which I created for the Ubuntu
package of Ghostscript 8.64 and it fixes the bug.
