netdata v2.2.0+ turning on LTO may cause crash

I updated netdata to v2.2.0 a few days ago and it crashed itself after running for a while.

I later compiled v2.2.1 based on PKGBUILD from the Arch repository and everything worked fine. Until today when I updated to ALHP/extra-x86-64-v3/netdata and it started crashing as before, I suspect it's a LTO issue as my makepkg.conf doesn't have LTO turned on.

I switched to extra/netdata v2.1.1 and everything works fine.
