Hi @pbiering,

Starting to work through these (slowly). Thanks again for sending in the patches.

For this one, I can replicate the exact issue when installing from the repos, but for some reason, not when I am compiling the 1.2.0 release from source myself. Did you manage to replicate the issue when building from source, too?

Wonder if there are some gcc/glibc changes which are triggering this issues.

In any case, it makes sense to exit the function early if there are just one entry anyway, so lets merge it. Although I am not 100% sure this is not related to some weird compiler shenanigans/glibc :-)

Merged here: 341eccc

Thanks for the PR, I will try to get around to the rest tomorrow!

Haven' tested because target is stability on EL8

as also compiled with "clang" has not bring up the issue I assume either huge code optimization or additional security mechanism inserted during compilation with gcc

I tested the new daily build (https://build.opensuse.org/package/binaries/home:naemon:daily/naemon-livestatus/CentOS_8_Stream) and it seems to work fine, so that's great news. Thanks again for the PR!
