Bug 588066 – sys-power/apcupsd-3.14.13 crash on power failure event

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description fkater 2016-07-05 12:36:13 UTC]

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:

Reproducible: Always

[Comment 1 fkater 2016-10-17 18:48:00 UTC]

The new version apcupsd-3.14.14 fixes the issue.

Test was:
- install new version
- pull out power from UPS.
- correct shutdown
- plug in power to UPS
- correct reboot
- check of previous demsg: no crash of apcupsd
