--- Comment #12 from Petr Pisar ppisar@redhat.com --- This happens even in Rawhide (perl-App-a2p-1.007-3.fc22.x86_64, perl-libs-5.20.1-315.fc22.x86_64). It starts to happen exactly since 2050 characters which are word characters.

--- Comment #13 from Ralf Corsepius rc040203@freenet.de --- I think this bug is caused by upstream having used a broken byacc to generate a2p.c.
Grabbing the missing yacc-source file a2p.y from upstream's git (https://github.com/Leont/app-a2p/a2p.y) and regenerating a2p.c using Fedora 21's byacc (byacc-1.9.20130925-4.fc21) seems to fix this issue for me.

--- Comment #15 from Fedora End Of Life endoflife@fedoraproject.org --- This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
