I updated davfs2 to 1.5.5 for F31+ Let me know if its working fine for you, so I can go ahead and upgrade also for F30/F29 and maybe EPEL. https://src.fedoraproject.org/rpms/davfs2/c/b5daac4efa37402af756931cd75ac5bb59ca214a?branch=master https://koji.fedoraproject.org/koji/taskinfo?taskID=36799564
With "davfs2-1.5.5-1.fc31.x86_64" there is no "SIGSEGV" anymore, but the command "umount <mountpoint>" does not do anything (the mountpoint will be still active).
Rudolf: if you are still seeing the problem with 1.5.5 I guess the best way to fix it is to create a support ticket upstream: http://savannah.nongnu.org/support/?group=davfs2

Filipe: I just noticed the comment by Mathias Habluetzel (https://bugzilla.redhat.com/show_bug.cgi?id=1710968#c3) who mentioned that we might be able to workaround this by using "-std=c89". Should submit a PR for this? @everyone: I could create a COPR pretty quickly and push an updated build if there are some testers who are willing to try these builds.
Rudolf: I just noticed that you marked this bug as "private". This makes it harder for other users to collaborate on a solution. Would you mind if we remove the "mark as private"?

Thanks for reporting back. quoting upstream's Werner Baumann https://savannah.nongnu.org/bugs/?56286#comment5 > The bug is fixed in the CVS-sources. I intend to do a bugfix release soon, but first want to fix at least one other bug. Maybe it is the easiest thing to wait a bit more or someone would have to extract the patch from CVS (*shudder*) so Fedora could ship that one on top of 1.5.5.
