apcupsd-3.14.13 crashes on power failure event. Tested with glibc-2.23-r2, gcc-5.4.0, with or without lto. There is /bin/mail installed but IMHO this does not cause the crash. apcupsd-3.14.8 does NOT crash, so do not remove that older version yet. This is what journalctl -b -1 has: Jul 05 13:03:45 p-710 apcupsd[260]: Running on UPS batteries.
