My Fedora 29 system received an update of the re2 package from re2-20160401-7.fc29.x86_64 to re2-20190801-1.fc29.x86_64. With the new package, I only receive an error message in Konqueror when accessing a web site because the Webengine KPart cannot be loaded any more: Es ist ein Fehler beim Laden von Modul Webengine aufgetreten. Die vermutliche Ursache ist: Cannot load library /usr/lib64/qt5/plugins/kf5/parts/webenginepart.so: (/lib64/libQt5WebEngineCore.so.5: undefined symbol: _ZN3re23RE23Arg9parse_intEPKciPv) $ c++filt _ZN3re23RE23Arg9parse_intEPKciPv re2::RE2::Arg::parse_int(char const*, int, void*) Apparently this library made an incompatible change to its interface and broke its dependencies this way. Downgrading only the re2 package back to re2-20160401-7.fc29.x86_64 fixes the problem for me.
Thanks for the report! Yes, that is a known issue, reported and tracked in https://bugzilla.redhat.com/show_bug.cgi?id=1672014

This message is a reminder that Fedora 29 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 29 on 2019-11-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '29'. 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 29 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.
