This is lacking some context, so here's more:
This was triggered on an arm64 system (Ampere eMAG), any sort of affinity
restriction suffices, e.g.
$ rteval -O -D -v --loads-cpulist=2-3
I can reproduce that on my x86 laptop:
$ sudo ./rteval-cmd -O -D -v --loads-cpulist=2-3
[DEBUG] [kcompile] systopology: 1 node system (8 cores per node)
[DEBUG] [kcompile] node 0 has no available cpus, removing
[DEBUG] [kcompile] node 0 has no available cpus, removing
[DEBUG] [hackbench] node 0 has no available cpus, removing
