Summary	0012343: collectd write_riemann always crashing on Rocky 9.7
Description	I'm getting stacktrace from collectd write_riemann plugin, which is using riemann-c-client, when collectd is trying to send metrics. I didn't have these issues before. Stacktrace details: ``` Process 4729 (collectd) of user 0 dumped core.

However, I'm running collectd 5.12.0 and riemann-c-client 1.10.4 on Debian 13 without any issue Also, rieman-c-client might need update on Rocky as well.
Steps To Reproduce	1. Install collectd, riemann-c-client and collectd-write_riemann 2. in /etc/collectd.conf enable line ``` LoadPlugin write_riemann ``` and add at the end of the file: ``` <Plugin write_riemann> <Node "riemann_client"> Host "127.0.0.1" Port 5555 Protocol TCP Batch true BatchMaxSize 8192 StoreRates true AlwaysAppendDS false TTLFactor 2.0 Notifications true CheckThresholds false EventServicePrefix "" </Node> </Plugin> ``` 3. Download riemann tar.bz2 archive from https://github.com/riemann/riemann/releases/tag/0.3.12 4. Extract it and run: ``` ./bin/riemann ``` 5. Start collectd. Every time it tries to send metrics, it will crash.
