Comment 1 Andrej Nemec 2017-11-03 13:27:12 UTC

Created rubygem-ox tracking bugs for this issue:

Affects: epel-7 [bug 1509283]
Affects: fedora-all [bug 1509284]

Comment 2 František Dvořák 2018-02-22 10:16:47 UTC

This could be probably closed? Fedora has the new version with the fix, EPEL 7 has the patch backported.

Quit check for this issue:

ruby -rox -e 'Ox.parse_obj("<k><s></s></k>")'
