Hi.
After turning on mod_http2 and enabling h2 protocol, I've noticed child crashes
approx. once per day:
[2016-07-08 21:07:10.035281] [core:notice] [pid 15804:tid 1] AH00051: child pid
1617 exit signal Segmentation fault (11), possible coredump in
/pub/apache/cores
[2016-07-09 18:13:12.624654] [core:notice] [pid 15804:tid 1] AH00051: child pid
675 exit signal Segmentation fault (11), possible coredump in /pub/apache/cores
Got two core dumps for now:

Tested with both 2.4.18/2.4.23, openssl 1.0.2g/1.0.2h.
If there's anything more I can do -- will be glad to help.
