Description James Bromberger 2018-11-12 16:43:28 UTC
Debian testing, today: Having enabled h2, tls 1.3, and mod_dav, when trying to access my SVN repo I get error log with "[pid 27505:tid 140218700837952] AH00052: child pid 27902 exit signal Segmentation fault (11)". My Protocols line in apache.conf is "Protocols h2 h2c http/1.1", but when I override this in the Listener for my SVN repo with "Protocols http/1.1" - it works as expected. I suspect that the mod_dav_svn does not like h2! Apache2: MPM event.
