[Bug]: SIGABRT netdata

[thiagoftsm]

Bug description

After we merge the PR https://github.com/netdata/netdata/pull/13646 I began to have SIGABRT on Raspberry PI when I stop netdata:

Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1".
Core was generated by `/usr/sbin/netdata --special-spawn-server'.
Program terminated with signal SIGABRT, Aborted.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

Expected behavior

Stop netdata without any issues.

Steps to reproduce

1. Compile netdata with flags CFLAGS="-Og -ggdb -Wall -Wextra -fno-omit-frame-pointer -Wformat-signedness -fstack-protector-all -Wformat-truncation=2 -Wunused-result -DNETDATA_INTERNAL_CHECKS=1 -D_FORTIFY_SOURCE=2 -DNETDATA_VERIFY_LOCKS=1"
2. Run netdata during few minutes, and stop it.
3. Run coredumpctl list to check if you have a SIGABRT

Installation method

from source

Additional info

An additional information, this is not happening everytime. I had to start and stop netdata frequently.
