Dimitris,

The issue appears to be lack of -lm linkage after a change in libc6 modf()
implementation in 2.42. However, it is only triggered in rsyslog builds without
systemd (hence only reports from  Devuan, Gentoo and Artix.)

It is fixed in libfastjson upstream[1]. Src:libfastjson is not forked in Devuan
and I have reopened the existing Debian bug[2] to request the fix be cherry-picked.
