Description Petr Pisar 2022-09-19 13:08:22 UTC 
qpdf-10.6.3-4.fc38 fails to build in Fedora 38 because tests fail like this:

qpdf 569 (check output)                                        ... PASSED
qpdf 570 (check non-static ID version)                         ... FAILED
--- Key functions, C API ---
qpdf 571 (C API info key functions)                            ... PASSED
[...]
qpdf test 570 (check non-static ID version) FAILED

A difference between passing and failing build root is at <https://koschei.fedoraproject.org/build/13660370>. This is very probably triggered by upgrading grep from 3.7-4.fc37 to 3.8-1.fc38. From grep-3.8 NEWS:

  The egrep and fgrep commands, which have been deprecated since
  release 2.5.3 (2007), now warn that they are obsolescent and should
  be replaced by grep -E and grep -F.
Comment 1 Zdenek Dohnal 2022-09-19 14:33:21 UTC 
Hi Petr,

thank you for reporting the issue!

I'm working on rebase to 11.1.0 ( https://bugzilla.redhat.com/show_bug.cgi?id=2125823 ) which doesn't show the error, so I'll fix this bug by the rebase.
Comment 2 Benjamin Herrenschmidt 2022-09-20 06:08:08 UTC 
Yes, it's fixed in 11.0.0 onwards by https://github.com/qpdf/qpdf/pull/761
Comment 3 Zdenek Dohnal 2022-09-22 12:13:23 UTC 
The rebase will take longer time, because the dependent packages are broken with new qpdf. I'll fix this before the rebase.
Comment 4 Zdenek Dohnal 2022-09-22 13:29:22 UTC 
Fixed by https://koji.fedoraproject.org/koji/taskinfo?taskID=92267780 .
